Hi Mike!

It seems that the fix for Bug 1401991 may have caused this regression.

Can you have a look into this?

Thanks!

Might be that my patch in bug 1407591 also solves this glitch.
I'll ask for verification once it lands.

No, but I don't see this issue anymore, regardless. I consider this fixed, would be nice if Emil can verify it!

Hi Mike!

This issue is verified fixed using Firefox 60.0a1 (BuildId:20180302104326) on Ubuntu 16.04 64bit.

It seems that this issue is reproducible using Firefox 59.0b14 (BuildId:20180301022608).

Unfortunately,this issue seems to be riding to release 59.

We already shipped this in 58, so this is unfortunate but I don't think there's much we can do at this point in the cycle. I expect some of Paolo's patches fixed this, but uplifting all of them to 59 at this point is too risky.
