Comment # 30 on bug 1015998 from Wolfgang Rosenauer

It will be summited with next Firefox update.
It's already fixed for 52.1 in the Mozilla repository and therefore will end up
in the update package in any case. Submitting a new package out of band I
didn't find important enough.
Actually just checked and next planned version arrives mid of June. So I
consider submitting a new package inbetween.
