When I run ./mach mochitest I get the following crash:

0:14.88 GECKO(85525) ^G[85525, Main Thread] ###!!! ASSERTION: Can't create an accessible for the document!: 'parentDocAcc', file /mnt/dev/moz/fission/accessible/base/DocManager.cpp, line 453

It appears to be after skippin the first few accessability tests, but happen in-between tests.

Weird. We shouldn't be able to get events from a document for which we can't create an accessible for the parent doc. I wonder why this doesn't show up in automation?
