Subject: [PATCH] [Regression] Ensure that documents with varying page sizes
 are initialized correctly (PR 15812 follow-up)

The rotation-caching added in PR 15812 completely breaks initialization of PDF documents with varying page sizes, causing all pages to wrongly get the same size; see e.g. `sizes.pdf` from the test-suite.
To fix that without having to e.g. add a new parameter, which feels error prone, this patch changes the `PDFPageView.#setDimensions` method to completely ignore the rotation-caching until the `setPdfPage`-method has been called.
