After clicking on a reader tab, the reader will get focused
but the default mousedown event handler can then shift
focus onto the actual tab. It looks like the focus gets "lost",
and breaks reader keyboard shortcuts so we want to avoid it.
Mainly happens on windows.

- If there are too many tabs opened to fit onto the screen,
the tabs menu can be scrolled
- When tabs menu is opened, scroll to the selected tab
- Use margins instead of padding to that the scrollbar does not
overlap with the cross button
- Make sure that if the tabs menu is long, there will
be a gap between it's top/bottom and the edge of the
screen
- On linux, screen.availTop and screen.availHeight are not always
correct and the menu can go outside of what is supposed to be
the available screen area. Special treatment for those
edge cases
Fluent seems to clear out label/placeholders attributes set directly
(not via .ftl file). So quicksearch placeholder added directly ends
up being emptied out.
This is the cleanest workaround found so far: add the placeholder
as the fluent argument
Fixes: #4073
- do not erase the last recorded tag on blur of the tag selector
- on tab from collectionTree or shift-tab from tag selector input,
try to refocus that last focused tag. If one does not exist,
try to focus the first non-disabled tag.

Locator type dropdown just has aria-label "Locator type".
The locator input is labelled by a hidden label with "Locator input"
string, as well as the locator type. That way both are announced
when it is focused.
Fixes: #4039
- vpat 57: remove tabindex values, set tabindex=0 on all focusable
fields. It allows mozilla to determine the best focus sequence
for keyboard navigation and fixes wrong order where some inputs would
go before the "Ok" and "Cancel" buttons and some - after
- vpat 58: added labels to all inputs to be announced when focused.
Added separate labels for locator menulist and for the locator input so
that the locator type has a proper label. It is also better to have
visible explicit labels when possible
Mostly for brevity, but also:
- "Down Arrow" → "space bar" because down-arrow doesn't open the
citation dialog with VoiceOver enabled -- it starts reading individual
words.
- In some cases (selected/open items and notes), Tab takes you to search
results without your needing to type something first.
