Given that this is a shadowed getter, the `opMap` is already lazily initialized and it shouldn't be necessary to *also* use the `getLookupTableFactory` helper function here. Looking at the history of the code, it seems that this is simply a leftover from before JavaScript classes existed.
Now that modern JavaScript is fully supported also in the worker-thread we no longer need to keep old closures, which slightly reduces the size of the code.

While this cache will not contain a huge amount of data in practice, it's nonetheless a *global* cache that currently will never be cleared.
This patch also removes the existing closure, since it shouldn't really be necessary nowadays given that the code is a JavaScript module which means that only explicitly listed properties will be exported.
When I started looking at PR 16938 it occurred to me that some of the new structTree-methods are synchronously accessing certain dictionary-data (not used during "normal" structTree-parsing), which may not be generally safe since everything in a dictionary could be a reference (and the relevant data may not have been loaded yet).
Rather than suggesting that we make all those new methods even more asynchronous, to me the overall simplest and safest solution is to ensure that the *entire* PDF document has been loaded *before* we begin saving it. In practice this shouldn't really affect "performance" of saving noticeably, since it's always depended on the entire PDF document being downloaded.
Finally note that with the exception of the PDF document possibly not having been fully downloaded when saving is triggered, all other "global" document properties are pretty much guaranteed to already be available at this point.
The unit test is re-enabled because it no longer seems to fail after 10
runs on Linux where this used to fail often. Code inspection also shows
that the code is correct and should raise the previous exception
(anymore). Finally, a lot has changed since this test was disabled such
as new Jasmine versions, new Linux bot OS version and new browser
versions.
While it makes sense to check that the `destDict` parameter is indeed a Dictionary, since that data comes from the PDF document itself, the `resultObj` parameter is an internal PDF.js implementation detail that should always be correct (or tests will fail).
Over time the amount of "document level" data potentially needed during parsing of Annotations have increased a fair bit, which means that we currently need to ensure that a bunch of data is available for each individual Annotation.
Given that this data is "constant" for a PDF document we can instead create (and cache) it lazily, only when needed, *before* starting to parse the Annotations on a page. This way the parsing of individual Annotations should become slightly less asynchronous, which really cannot hurt.
An additional benefit of these changes is that we can reduce the number of parameters that need to be explicitly passed around in the annotation-code, which helps overall readability in my opinion.
One potential drawback of these changes is that the `AnnotationFactory.create` method no longer handles "everything" on its own, however given how few call-sites there are I don't think that's too much of a problem.
The classes were stripped out during when creating the field name but
it led to a wrong name.
Since class components in a path are irrelevant, they're just ignored
when searching for a node in the datasets.
Focus callback must be called only when the element has been blurred.
For example, blur callback (which implies some potential validation) is not called
because the newly focused element is an other tab, an alert dialog, ... so consequently
the focus callback mustn't be called when the element gets its focus back.
While reviewing PR 16898 it occurred to me that it's currently impossible to trigger downloading of FileAttachment annotations using the keyboard.
Hence this patch adds `Ctrl + Enter` as the keyboard shortcut to download those, thus supplementing the existing double-clicking when using a mouse.
The goal is to always have something which is focusable to let the user select
it with the keyboard.
It fixes the mentioned bug because, the annotation layer will now have a container
to attach the canvas for annotations having their own canvas.
