Comment on attachment 636041 [details] [diff] [review] patch [Approval Request Comment] If Bug 763308 becomes approval then this patch should also becoming it to solve the issue on standalone window.
Due to test failures from bug 755793 landing, I had to back this out: https://hg.mozilla.org/comm-central/rev/b7dd4a4421e4
Asking again for check-in as this patch shouldn't be cause of the failures.
I'm unable to reproduce those failures locally. I've pushed both this and bug 766793 to try, just in case. https://tbpl.mozilla.org/?tree=Thunderbird-Try&rev=140b51b72e6c
Hm, those failures are showing up in the try build. Curious.
