PTAL
Note: this solves the crash issue, but e.g. some input elements like dropdowns
use Mac native library, so they get displayed on screen. I'm unsure if this can
be prevented.

No L-G-T-M from a valid reviewer yet.
CQ run can only be started once the patch has received an L-G-T-M from a full
committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,_not_ a
full super star committer.
Committers are members of the group "project-chromium-committers".
Note that this has nothing to do with OWNERS files.
