Notes

Getting the crash signature into these bug reports is a TODO; sorry

These updates will be on mozilla-central once bug 1793052 lands.

Note: this bug is for tracking fixing the issues and is not
owned by the wpt sync bot.

This bug is linked to the relevant tests by an annotation in
https://github.com/web-platform-tests/wpt-metadata. These annotations
can be edited using the wpt interop dashboard

If this bug is split into multiple bugs, please also update the
annotations, otherwise we are unable to track which wpt issues are
already triaged. Resolving as duplicate or closing this issue should
be cause the bot to automatically update or remove the annotation.

[Andreas Pehrson [:pehrsons]]

The crashes mentioned here and in bug 1793052 are bug 1788563. It is debug-only and triggered by one of the RTC_DCHECKs in MouseCursorMonitorWin::Init, can't really say which.
