Nika, could you please take a look at this? It seems to be a regression from https://bugzilla.mozilla.org/show_bug.cgi?id=1582237

The fuzzers have found a test case that can consistently reproduce this issue. Would a reduced version of if be useful to land as a crash test?

Yes! It'd be awesome to have an example which could reliably reproduce this :-).
Is there any chance you could file a follow-up bug, attach the fuzz test case to it, and needinfo me?
