This crash is happening fully within Windows code for users that have accessibility enabled. I'm unsure what might be causing it, maybe the correlations will give some clue. Filing this even though it might not be our fault so that we can track the volume.

Severity: -- → S3

This looks fairly frequent on beta 90. We might want to revisit the severity?
