As per the comments it isn't supported with cache-the-world on, it's barely documented if at all, and a test for it seems to be failing without me being able to reproduce it at least (tried on both windows and Linux). I don't think it's worth digging too much more into it. My guess is a reentrant / differently timed a11y event caused by my scheduling changes, or so, which would override sEventTargetNode or the other static bool. The test has ~always failed on macOS too... Differential Revision: https://phabricator.services.mozilla.com/D210872
