Flags: in-testsuite?

Please let me know if a Pernosco session would be helpful and I will create one.

Fwiw, in a debug build I get:
###!!! ASSERTION: The meter frame should have a child with a frame!: 'barFrame', file layout/forms/nsMeterFrame.cpp, line 97

Is this a regression?

Priority: -- → P2

This is fixed by https://phabricator.services.mozilla.com/D44808, which is awaiting your review, fwiw.

Depends on: 1578844

OK, good. No need for a regression-window then.
