1723552 - Add some WPTs for language-dependent system-ui font behavior

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, task)

Description

[Jonathan Kew [:jfkthame]]

+++ This bug was initially created as a clone of Bug #1722488 +++

font-family: system-ui should render as the appropriate UI font for the script and language of the content, not just to a single default font (e.g. based on system locale).

Currently only Safari's implementation handles this; in Chrome and Firefox (with the support implemented in bug 1720710 + bug 1722009) the behavior is incomplete.

I've created a few tests that exercise this aspect. Currently they pass only in Safari, but I'd like to get them landed so that we have a target to work towards.

(Not sure how meaningful these tests are on non-Mac platforms at the moment. I've pushed a try run to see how they fare...)
