Re: [csswg-drafts] [css-pseudo-4] UA must (instead of should) use the OS-default highlight colors ... (#4785)

> OS-default highlight colors are not well defined,

OS-default highlight colors can be user-settable, therefore they can not be predictable. This was the case in Windows XP and it is the case in KDE3 and KDE4 (and probably other desktop environments and possibly with browser themes) in Linux.

> not really testable

The repository has now 2 tests:
http://test.csswg.org/suites/css21_dev/nightly-unstable/html4/system-colors-001.htm
which is a manual test
and
http://wpt.live/css/css-color/parsing/system-color-valid.html

I do not know about other OSes, other platforms and other devices. So I can not comment on this.

My understanding is that #4720 only relates to presence of fill/stroke ... which only apply to SVG objects.
