Investigated further and noticed that this issue is a regression: - Last good revision: dac5700acf8b (2012-10-17) - First bad revision: cb573b9307e5 (2012-10-18) - Pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=dac5700acf8b&tochange=cb573b9307e5 - I suspect that this issue is regressed by Bug 801280

I just landed the upstream update - redirecting to bdahl for investigation.

This should be fixed in tomorrow's nightlies. Not sure this is severe enough to warrant worrying about backporting to 45/46, though.

Confirm that this issue is fixed on latest Firefox 47.0a1 (2016-02-21) under Windows 10 64-bit, Ubuntu 14.04 32-bit and Mac OS X 10.9.5.

Since this is in nightly, can the right owner mark it FIXED? I agree this is not a candidate for uplift.
