The `AnnotationLayer` may not display correctly formatted data in PopupAnnotations, especially in the GENERIC viewer, since it's using native methods[1] that depend on the *browser* locale instead of the viewer locale as intended.
With Fluent we're able to improve things since it's got built-in support for formatting dates. Not only does this simplify the JavaScript code slightly, but it also gives the localizer more fine-grained control of the desired output.

The `PDFDocumentProperties` dialog may not display correctly formatted data, especially in the GENERIC viewer, since it's using native methods[1] that depend on the *browser* locale instead of the viewer locale as intended.
At the time when this dialog was introduced that was probably all we could easily do, but with Fluent we're able to improve things since it's got built-in support for formatting numbers and dates. Not only does this simplify the JavaScript code, but it also gives the localizer more fine-grained control of the desired output.

Currently we *manually* fetch the "pdfjs-additional-layers" string and update the DOM-element, which was needed since we want to avoid triggering a bunch of otherwise unnecessary translation when appending the entire layer-tree to the DOM.
By introducing a new helper method in the `L10n`-class we can avoid this, and instead use a "data-l10n-id" attribute on the element (as most other viewer code does nowadays).
Given the length of the l10n-strings we can slightly reduce verbosity, and thus overall code-size, by introducing a helper method for fetching l10n-data.
While testing this I stumbled upon an issue in the `L10n`-class, where an optional chaining operator was placed incorrectly since the underlying method always return an Array; see 48e2a62ed4/fluent-dom/src/localization.js (L38-L77)
- When adding page dict candidates to the lookup tree, also initiate fetching them from xref, so if they are not yet loaded at all, the XHR will be sent
- Only at the top level - assume that if there is a /Pages tree, it is sensibly structured and the number of requests won't be too bad
- We can then await on the cached Promise without making the requests pipeline
- This has a significant performance improvement for load-on-demand (i.e. with auto-fetch turned off) when a PDF has a large number of pages in the top level /Pages collection, and those pages are spread through a file, so every candidate needs to be fetched separately
- PDFs with many pages where each page is a big image and all the pages are at the top level are quite a common output for digitisation programmes
- I would have liked to do something like "if it's the top level collection and page count = number of kids, then just fetch that page without traversing the tree" but unfortunately I agree with comments on #8088 that there is no good general solution to allow for /Pages nodes with empty /Kids arrays
Given that we handle non-embedded Calibri fonts as "mapped to standard font", we really ought to be able to use the same glyph mapping as for an actual standard font.
Note that this actually improves consistency in the code, given how we already handle such fonts if they happen to be of the `CIDFontType2` type; see b47c7eca83/src/core/fonts.js (L1186-L1190)
This integration test fails intermittently because we cache the initial
total value to be able to compare it to the new total value at the end
of the test to check that it's different before doing the assertions.
However, this doesn't work as expected because the second `clearInput`
call triggers an intermediate total value calculation because it clicks
on another input field and that triggers a sandbox event.
This results in the `waitForFunction` calls always resolving immediately
and since we don't use other means of waiting until the calculation is
done (using e.g. `waitForSandboxTrip`) we basically rely on the time
between the final click and the assertions to be enough for the sandbox
to do its work. If it's is not done in that time, we do the assertions
with older values and that makes the test fail.
This commit fixes the issue by simply waiting for the total value to be
what we expect it to be. This requires less code, is more consistent
with the other integration tests and removes the possibility of doing
assertions against older values.
In PR #18574 setting `window.uiManager` was moved into the `src` folder
to avoid intermittent integration test failures because at the time we
lacked a way to register event listeners early (before PDF.js loads).
However, in PR #18617 this functionality got introduced, so we can now
use the new way of setting up the event bus in the tests to move this
back to the `test` folder again and to reduce the amount of test-only
code in the main codebase as discussed in PR #18574.
Partially reverts e037c5711d.
The function evaluateOnNewDocument in Puppeteer allow us to execute some js before the pdf.js one
is loaded.
It allows us to stub some setters before there are used and then set some event handlers very soon.
We introduced quite a few new strings recently, but during the last few
rounds of updates we didn't see new translations updates becoming
available. I only just now recalled the announcement that Mozilla is
moving from Mercurial to Git, and indeed the Mercurial page at
https://hg.mozilla.org/l10n-central hasn't been updated since July
anymore and that's were we used to pull our translations from.
This commit fixes the issue by changing the URLs to the Mozilla Git
repositories hosted on GitHub instead.
The way that the debugging hash-parameter parsing is implemented leads to a lot of boilerplate code in this method, since *most* of the cases are very similar.[1]
With just a few exceptions most of the options can be handled automatically, by defining an appropriate checker for each option.

[1] With the recent introduction of TESTING-only options the size of this method increased a fair bit.
The problem seems to be caused by the browser trying to "restore" editing input-elements, in the various toolbars, to their previous values when the tab is re-opened.
Hence the simplest solution appears to be to move the event handling into the editor-code, which is also less code overall, since the listener thus won't be registered early enough for the problem to appear.
This patch allows embedders of PDF.js to provide custom match
logic for seaching in PDFs. This is done by subclassing the
PDFFindController class and overriding the `match` method.
`match` is called once per PDF page, receives as parameters the
search query, the page contents, and the page index, and returns
an array of { index, length } objects representing the search
results.
This commit fixes a regression from #18596 where the "Add image" button
styles broke because it's a labeled toolbar button but the labeled
toolbar button CSS rules were only scoped to the secondary toolbar.
However, nowadays labeled toolbar buttons are also used in e.g. the
editor parameters toolbar, and this highlighted that we didn't clearly
encode the concept of labeled toolbar buttons in the CSS so far.
This patch extracts the CSS rules for labeled toolbar buttons that were
previously limited to the secondary toolbar into a dedicated generic
class that can be applied on top of any unlabeled toolbar button to
convert it to a labeled toolbar button, regardless of its position in
the DOM. This also makes the distinction clearer in the HTML, and the
new CSS scope for the toolbar buttons lays the foundation for combining
the other toolbar buttons rules in there later on.

Using the `:is(a)` selector we can move the previously separate rules
into the main `.toolbarButton` override rules.
