4fda2526f4 Send combination keysyms for some Japanese keys 
Windows doesn't give us stable symbols for a bunch of Japanese IM keys,
instead alternating between two symbols. This state is not synchronised
with the IM running on the remote server so to have stable behaviour we
have to collapse these multiple symbols in to a single keysym.

8b8201fd73 Remove Firefox Alt workaround 
The bug got fixed way back in Firefox 63, and it is also misbehaving
with modern Firefox as they no longer consider AltGr an Alt-key.

33a113a475 Handle empty rects in RAW decoder as well 
It was overlooked in the previous commit because we couldn't feed
empty data messages through the test framework.

073737c8ac Handle empty rects from the server 
These are very pointless for the server to send, but not a violation of
the protocol so we need to be able to handle them. We've seen this
happen in real world scenarios a few times.

7412dde8ee Handle quick Cursor detach after mouse up 
This timer might fire after the Cursor object has detached from a DOM
element, causing crashes. This will likely not happen in real scenarios,
but the tests are quick enough to trigger this.

LDAP or other extensible authentication mechanisms)

Tested with TigerVNC server (Xvnc -SecurityTypes Plain -PlainUsers '*')

b173c8854a Fix crash with too large clipboard data 
If too much text is copied in the session, String.fromCharCode.apply()

this issue by avoiding apply() altogether. Also added test to cover this
issue.

ad206180d2 Properly detect scrollbar gutter 
As a rule, instead of hard-coding a behavior on specific platforms we
should do dynamic detection.

This commit moves away from always hiding scrollbars on Android and iOS
and instead detects the rendered width of scrollbars in the browser.
