(offtopic: I noticed this bug while checking bug 1347184 comment 46.)

The loading icon got microscopic / cut off / invisible.
(Only the loading icon of the second tab is relevant. You don't need to do anything.)

I haven't confirmed, but I suspect this to be the same bug as https://bugzilla.mozilla.org/show_bug.cgi?id=1435143 (I've added some more details in that bug).

Fixed in the try build from bug 1435143 comment 7.

[Milan Sreckovic [:milan] (needinfo for best results)]

This being fixed with a PR - is there a Gecko side reftest that we can add that catches this problem?
