crashes with this signature started taking off around the beginning of 2017 - they affect 32bit versions of win7 and upwards (but mostly windows 10).

correlations for this signature primarily hint at the IME module "wnTSF.ime" and other parameters that might be typical for chinese users...

Moving all open keyboard/IME handling bugs to DOM: UI Events & Focus Handling component.

Clearing the old needinfo - the bug was closed a while ago, and I don't see pending actions/questions.
