For provenance, enabled in PR #18352, to work the repository URL in
`package.json` is required to match the repository URL of the GitHub
Actions invocation. This should fix the following error we encountered
publishing a new release today:
```
npm error 422 Unprocessable Entity - PUT https://registry.npmjs.org/pdfjs-dist - Error verifying sigstore provenance bundle: Failed to validate repository information: package.json: "repository.url" is "git+https://github.com/mozilla/pdfjs-dist.git", expected to match "https://github.com/mozilla/pdf.js" from provenance
```
It should help to have such a garbage in the logs:
```
console.warn: TopSitesFeed: Failed to fetch data from Contile server: NetworkError when attempting to fetch resource.
JavaScript error: , line 0: TypeError: NetworkError when attempting to fetch resource.
```
This PR switches from `npm install` to `npm ci` on CI. This enables some additional checks to ensure repo integrity when using CI/CD.

This commit removes the following warnings from the `npm publish` output:
```
npm warn publish npm auto-corrected some errors in your package.json when publishing. Please run "npm pkg fix" to address these errors.
npm warn publish errors corrected:
npm warn publish Removed invalid "scripts"
npm warn publish "repository.url" was normalized to "git+https://github.com/mozilla/pdfjs-dist.git"
```
For the "scripts" section it turns out that if the package doesn't have
any scripts it's expected to explicitly set it to an empty object; refer
to https://github.com/npm/cli/issues/6918 and
https://github.com/denoland/dnt/pull/414.
Errors related to this `requestAnimationFrame` show up intermittently when running the integration-tests on the bots, however I've been unable to reproduce it locally.
Hence I cannot guarantee that it's enough to fix the timing issues, however this should be generally safe since the `requestAnimationFrame` invokes the `_next`-method and the first thing that one does is check that rendering hasn't been cancelled.
While the event listener is removed during testing, the `requestAnimationFrame` isn't cancelled and that occasionally shows up when the integration-tests are run on the bots.
Debugging #17931 uncovered a race condition in the way we use the
`waitForEvent` function. Currently the following happens:
1. We call `waitForEvent`, which starts execution of the function body
and immediately returns a promise.
2. We do the action that triggers the event.
3. We await the promise, which resolves if the event is triggered or
the timeout is reached.
The problem is in step 1: function body execution has started, but not
necessarily completed. Given that we don't await the promise, we
immediately trigger step 2 and it's not unlikely that the event we
trigger arrives before the event listener is actually registered in the
function body of `waitForEvent` (which is slower because it needs to be
evaluated in the page context and there is some other logic before the
actual `addEventListener` call).
This commit fixes the issue by passing the action to `waitForEvent` as
a callback so `waitForEvent` itself can call it once it's safe to do so.
This should make sure that we always register the event listener before
triggering the event, and because we shouldn't miss events anymore we
can also remove the retry logic for pasting.
The integration tests are currently not consistent in how they do
copy/pasting: some tests use the `kbCopy`/`kbPaste` functions with
waiting for the event inline, some have their own helper function to
combine those actions and some even call `kbCopy`/`kbPaste` without
waiting for the event at all (which can cause intermittent failures).
This commit fixes the issues by providing a set of four helper functions
that all tests use and that abstract e.g. waiting for the event away
from the caller. This makes the invididual tests simpler and consistent,
reduces code duplication and fixes possible intermittent failures
due to not waiting for events to trigger.
Browsers have an accessibility option that allows user to enforce
a minimum font size for all text rendered in the page, regardless
of what the font-size CSS property says. For example, it can be
found in Firefox under `font.minimum-size.x-western`.
When rendering the <span>s in the text layer, this causes the
text layer to not be aligned anymore with the underlying canvas.
While normally accessibility features should not be worked around,
in this case it is *not* improving accessibility:
- the text is transparent, so making it bigger doesn't make it more
readable
- the selection UX for users with that accessibility option enabled
is worse than for other users (it's basically unusable).
While there is tecnically no way to ignore that minimum font size,
this commit does it by multiplying all the `font-size`s in the text
layer by minFontSize, and then scaling all the `<span>`s down by
1/minFontSize.
This code contains the same bug that the previous commit fixed in
`waitForEvent`, namely that we don't clear the timeout if the event
is triggered. By using the now fixed `waitForEvent` function we not
only deduplicate this code but we also fix this issue so that no
incorrect timeout logs show up anymore.
Debugging #17931, by printing all parts of the event lifecycle including
timestamps, uncovered that some events for which a timeout was logged
actually did get triggered correctly in the browser. Going over the code
and discovering https://stackoverflow.com/questions/47107465/puppeteer-how-to-listen-to-object-events#comment117661238_65534026
showed what went wrong: if the event we wait for is triggered then
`Promise.race` resolves, but that doesn't automatically cancel the
timeout. The tests didn't fail on this because `Promise.race` resolved
correctly, but slightly later once the timeout was reached we would see
spurious log lines about timeouts for the already-triggered events.
This commit fixes the issue by canceling the timeout if the event we're
waiting for has triggered.
Currently errors in `afterAll` are logged, but don't fail the tests.
This could cause new errors during test teardown to go by unnoticed.
Moreover, the integration test use a different reporting mechanism which
also handled errors differently (this is extra reason to do #12730).
This patch fixes the issues by consistently handling errors in
`suiteStarted` and `suiteDone` in both reporting mechanisms.
Fixes#18319.
