The bug was supposed to be fixed by #20471 but here there are some annotations in the pdf.
When those annotations are added to the DOM, the struct tree has to be rendered but without
the text layer (because of asynchronicity).
So this patch is making sure that the modifications in the text layer are done once the
layer is rendered.
Update the styles and HTML to reflect the new views manager concept.
For now, nothing about split/merge functionality is implemented or visible.
The new styles for the outline, attachments, and layers will be added later.
The thumbnail view is now accessible with the keyboard.
By setting `display: contents` on `.markedContent` containers, they stop
affecting the layout of their children. This means that we can always
position text layer `<span>` elements using percentages relative to the
page dimensions, rather than having two separate code paths.
For some reason this breaks the workaround for text selection flickering
in Chrome/Safari, which can be fixed by setting `user-select: text` on
the `.endOfContent` div (only in Chrome/Safari, as it would break
selection in Firefox).
This commit moves all the logic to scale up&down `<span>`s in the text
layer, introduced in #18283, to CSS.
The motivation for this change is that #18283 is still not enough for
all cases. That PR fixed the problem in Chrome&Firefox desktop, which
allow users to set an actual minimum font size in the browser settings.
However, other browsers (e.g. the Chrome-based WebView on Android) have
more complex logic and they scale up small text rather than simply
applying a minimum.
A workaround for that behavior is probably out of scope for PDF.js
itself as it only affects not officially supported platforms. However,
having access to the actual expected font height (through
`--font-height`) allows embedders of PDF.js to implement a workaround by
themselves.
The goal is to be able to catch the errors before making a release.
And fix some css issues (especially the missing css code for the newly added menu.css)
This way, the screen readers can read the math content properly.
The elements in the text layer will also have aria-hidden="true"
to avoid duplication.
For now its use is limited to the comment sidebar but it'll be used for the new one
containing the thumbnails.
And make the sidebar more accessible with the keyboard or a screen reader.
The linter found some issues in viewer.html with </input> which isn't required
and a missing closing div in test/resources/reftest-analyzer.html.
The HTML can now be nicely formatted. In order to not break the build for
mozilla-central, the preprocessor has been fixed in order to take into account
the white spaces at the beginning of a comment line.
And finally, make .prettierrc (which is supposed to be either json or yaml)
itself lintable.
Clear the pointer type of CurrentPointers outside of the DrawingEditor to always keep the same, until the user changes the mode.
One of the goal is to keep the same pointer type in case of a refresh of the page or if the user changes the pdf document.
