Drop an external PDF anywhere in the views-manager thumbnail
sidebar to merge it at the cursor, rather than always inserting
after the current page via the "Add file" button.
The drop reuses the blue separator from page-move drag so the
user can see exactly where the inserted pages will land, and the
merge path is shared with the existing picker so post-merge
selection/current-page behavior stays consistent.

(“In HCM, the text selection is barely visible”).
Continues work from @calixteman who had a partial patch.
This PR improves viewer text-selection highlighting by rendering
selection shapes in the draw layer.
* add selection overlay rendering in the draw layer
* significant code relates to selections spanning multiple text
layers/pages, and edges/end-of-content boundaries
* clear selection on rotate/scale/scroll/spread changes
My main question is: how should it appear?
I don’t have access to the Figma file linked on bugzilla.
In the CSS (`draw_layer-builder.css`) there are 3 blocks:
* default
* `@supports` for browsers supporting `backdrop-filter`
* `forced-colors` mode
So it’s possible to design for those (or more).
Personally, the `backdrop-filter: invert(1)` is the most contrast,
so perhaps it’s better to use something else as the default,
and to use `invert(1)` if high contrast mode is used (maybe with a
`prefers-contrast` media query instead)?
If the active page is corrupt that currently results in the entire dialog being "blank", thus providing no information, which seems unfortunate and it's easy enough to only skip `pageSizeField` in that rare case.
Improve test coverage for multi-page documents, to ensure that:
- Unnecessary re-parsing is avoided where possible.
- Rotation, in the viewer, is handled correctly.
- Different page sizes are handled correctly.
It looks like this test passes consistently again, most likely after a
combination of browser/Puppeteer/configuration updates and the completed
switch to the WebDriver BiDi protocol.
Fixes#20136.
The custom solution for obtaining the bounding box of a given element
that we have now was necessary during the original introduction of the
integration tests because at the time the `ElementHandle.boundingBox()`
API in Puppeteer didn't work correctly in Chrome.
However, `getRect`, where this is used, is a hot utility function
because most tests call it multiple times, either directly or indirectly
via other utility functions, and it turns out that the approach we use
is slower than the native `ElementHandle.boundingBox()` API.
Fortunately, most likely after a combination of Chrome/Puppeteer updates
and the conversion to the formalized WebDriver BiDi protocol the custom
solution is no longer necessary because all tests pass without it too,
so this commit converts `getRect` to use `ElementHandle.boundingBox()`
instead to speed up the tests.
Note that for the integration tests the coverage information ends up
being processed in the Node.js context where `window` is not available,
so we use `globalThis` instead for the function that merges individual
test's coverage information into the global object because that is
available in all contexts we support. For clarity we also rename said
function since we're not exclusively dealing with `window` nor worker
data anymore.
The thumbnails are only available if the first page is ready, and not
awaiting that causes the drag-and-drop action to be performed using
incorrect thumbnail viewer state (see the analysis in #21184 for more
details).
Fixes#21184.
Supersedes #20902.
Unblocks #21173.
The `textLayerImagePlaceholder` canvas added in #20626 covers scanned
pages and was not recognized as a valid pointerdown target by
`#textLayerPointerDown`, so free highlights couldn't start.
When pages carry explicit pageIndices (e.g. after a delete),
resolve insertAfter against that layout instead of the empty
base sequence. Also reject partial pageIndices combined with
insertAfter, which would race against the extraction's auto-fill.
Many `parseInt` call-sites already provide the `radix` argument, and this rule helps improve consistency in the code-base; see https://eslint.org/docs/latest/rules/radix
*Please note:* The rule is disabled in `src/scripting_api/util.js` for now, since it's not obvious at a glance (at least to me) what the correct `radix` argument should be there.
Screen readers like NVDA fire synthetic click events on the <img> child of the button rather than on the
thumbnailImageContainer element itself, so the strict classList.contains check silently failed.
The alpha feature is available in Firefox nightly (with the pref `dom.forms.html_color_picker.enabled` set to `true`).
It's available in Safari but not in Chrome.
In PR #20887 the issue got fixed partly, but two issues remained that
unintendedly left room for intermittent failres:
- in the "Ctrl+ArrowLeft/Right" loop the `waitForBrowserTrip` call was
placed _before_ the actual keypresses, which means that for the final
iteration of the loop the last key presses were not properly awaited;
- in the "ArrowLeft/ArrowRight" loop the `waitForBrowserTrip` call was
absent, which means that we didn't wait for key presses at all.
This commit fixes the issues by consistently waiting to a browser trip
_after_ each key press to make sure the sidebar got a chance to render.
There is generally a small amount of time between the find call being
reported as finished and the find count results text being updated with
the correct number in the DOM, so the integration tests will fail if we
check the find results count text too soon.
This commit fixes the issue by using the `waitForTextToBe` helper
function to wait until the find count results text is what we expect it
to be. Note that we already use this helper function for this exact
purpose in other integration tests (related to reorganizing pages), and
it's also a little bit shorter/easier to read which cannot hurt.
