- Fix a typo in order to open the pdf in issue #13679
- After fixing the fill default color there wer some regressions because of z-index
and when fixing z-index there were some regressions because of borders
- So fix the borders rendering.
The PDF.js API has only ever supported accessing the original file ID, however the second one that (should) exist in *modified* documents have thus far been completely inaccessible through the API.
That seems like a simple oversight, caused e.g. by the viewer not needing it, since it really shouldn't hurt to provide API-users with the ability to check if a PDF document has been modified since its creation.[1]
Please refer to https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf#G13.2261661 for additional information.
For an example of how to update existing code to use the new API, please see the changes in the `web/app.js` file included in this patch.
*Please note:* While I'm not sure if we'll ever be able to remove the old `PDFDocumentProxy.fingerprint` getter, given that it's existed since "forever", that probably isn't a big deal given that it's now limited to only `GENERIC`-builds.

[1] Although this obviously depends on the PDF software following the specification, by updating the second file ID as intended.
Using `instanceof Object` is generally problematic, since it's not guaranteed to always do the right thing for all Objects.
(I stumbled upon this while working on another patch, when I noticed that the `outlineView` was broken with workers disabled.)
- support paragraph margins, line height, letter spacing, ...
- compute missing dimensions from fields based almost on the dimensions of caption contents.
- it aims to fix#13583;
- fix the switch to breakBefore target;
- force the layout of an unsplittable element on an empty page;
- don't fail when there is horizontal overflow (except in lr-tb);
- handle correctly overflow in the same content area (bug 1717805, bug 1717668);
- fix a typo in radial gradient first argument.
Given that this property is only used with password protected documents, and is consequently document-specific rather than viewer-specific, ensure that `IPDFLinkService.externalLinkEnabled` is actually being reset by `PDFViewerApplication.close`.
To make things less confusing/inconsistent, remove the *undocumented* `externalLinkEnabled` property from the `PDFLinkService` constructor and force it to always be manually set when needed.
- when the CSS line-height property is set to 'normal' then the value depends of the user agent. So use a line height based on the font itself and if for any reasons this value is not available use 1.2 as default.
- it's a partial fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1717681.
This patch provides an overall simpler *and* more consistent way of handling the `viewport` parameter during printing of XFA forms, since it's now again guaranteed to always be an instance of `PageViewport`.
Furthermore, for anyone attempting to e.g. implement custom printing of XFA forms this probably cannot hurt either.
Given that the "print"-intent is special, and that we should always fallback to the "display"-intent, let's ensure that the code actually reflects that.
Also, ensure that the method always returns a `Promise` since that's what the documentation says.
The `web/ui_utils.js` file should be usable from basically anywhere in the `web/`-folder, hence it should ideally not have any dependecies on its own and particularily *not* onces that pull in entire (large) factories.
This extends the approach in PRs 12848 and 13606 to also apply to the `xfaLayer`, since otherwise XFA forms will be similarly broken in most non-default scroll/spread modes.
Note that as far as I can tell, this is *not* a regression but rather a bug which has existed since basically "forever".
**In order to reproduce this easily:**
- Open the viewer.
- Set the zoom level to `400%`,
- Search for "expression".
The problem here is that when scrolling matches into view, we're scrolling to the start of the *containing* `textLayer` element rather than the start of the highlighted match itself.[1] When the entire width (or at least most) of the page is visible in the viewer, that doesn't really matter though which is likely why this bug has gone unnoticed for so long.[2]
Given that the highlighted match can be placed anywhere, e.g. even at the very end, within its `textLayer` element it's quite easy to see why the current implementation becomes a problem at higher zoom levels. All of this is then *further* exacerbated by `PDFFindController.scrollMatchIntoView` using a negative left offset, to ensure that the current match has some (visible) context available once scrolled into view.
In order to address this long-standing bug, we'll determine the (left) offset of the `selected` match and use that to modify the final position scrolled to in `PDFFindController.scrollMatchIntoView` such that the match is visible regardless of zoom level.
---
[1] Unfortunately we cannot directly scroll to the `selected` match, since it's not absolutely positioned and changing that would cause other bugs/regressions (note recent patches in that area).
[2] I did actually stumble upon this problem a little while ago, while working on PR 13482, but forgot to look into this again until I saw the new issue.
With the introduction of `PDFScriptingManager._closeCapability` in PR 13074, the pre-existing `PDFScriptingManager._pageEventsReady` boolean essentially became redundant.
Given that you always want to avoid tracking closely related state *separately*, since it's easy to introduce subtle bugs that way, we should just remove `PDFScriptingManager._pageEventsReady` now.
Obviously I *should* have done this already back in PR 13074, sorry about the churn here!
- a checkbox or radio doesn't have to be rescaled when the container is large so give the extra space to the caption to avoid some word wrapping.
- when the caption is on the right, then put ui on the left as first element and so remove flex:row-reverse stuff.
- some elements weren't displayed because their rotation angle was not taken into account;
- fix box model (XFA concept):
- remove use of outline;
- position correctly border which isn't part of box dimensions;
- fix margins issues (see issue #13474).
- move border on button instead of having it on wrapping div;
This code was added in PR 3968, apparently in order to fix scrolling of search results in HiDPI-mode.
However, after PR 4570 nothing is setting these `dataset`-properties any more and this is thus dead code which should be removed. (If that change had broken scrolling of search results in HiDPI-mode, you'd really expect that it'd been reported and fixed a long time ago.)
I missed this during review, since some of the changes in `web/pdf_print_service.js` broke printing.
Also, as part of these changes the patch replaces what looks like unnecessary `setAttribute` usage with "regular" `className` assignment and finally updates a couple of the CSS-rules to be more consistent.
