[Ryan Hunt [:rhunt]]

I'm having a difficult time reproducing this with that test case. (Fedora, Firefox ESR 53.7.3).

Is there anything else I need to do to reproduce this? Does this also reproduce in Nightly?

I can confirm that this still triggers on the lastest esr52 release but not on m-c.  My test system is Ubuntu 16.04 x64.  I've attached the prefs I used to trigger this issue.
