This can also be solved with #24521 but I don't see it being resolved in the near term.

In 60, my hope is that fixing this will fix that one also.

Unfortunately the ticket linked by Tom was fixed on 61, backport maybe? (I'm encountering this bug with TB 8.0a9 FWIW)

Actually, we'd need the fix for https://bugzilla.mozilla.org/show_bug.cgi?id=1453916 as well. So, hrm.

9.0a6, which is about to get built, is based on ESR 68, so closing.
This maybe (hopefully) corresponds to https://bugzilla.mozilla.org/show_bug.cgi?id=1412961
In 60, my hope is that fixing this will fix that one also.
