This bug was filed from the Socorro interface and is report bp-a05609ae-5e6e-4f50-a540-4c50e2170310. ============================================================= There is 1 crash in nightly 55 with buildid 20170309030216. In analyzing the backtrace, the regression may have been introduced by patch  to fix bug 1345362.  https://hg.mozilla.org/mozilla-central/rev?node=8fc5d55b1e9dc7ccea234d5c10be6da41ccaef7c
If this is actually crashing on the line it claims (the aSelf->GetAdditionalStyleContext() line), that doesn't seem related to bug 1345362.

According to <https://crash-stats.mozilla.com/signature/?_sort=-date&signature=mozilla%3A%3AElementRestyler%3A%3ARestyleSelf&date=%3E%3D2017-04-06T19%3A00%3A08.000Z&date=%3C2017-04-13T19%3A00%3A08.000Z>, we've got crashes with this signature going back quite aways. I don't think this is a regression 55 introduced, but should probably just be treated as a bug.
ElementRestyler is gone.
