Please review the bug and re-add the keyword for further analysis.

I wasn't able to reproduce this locally, either, on a build from 1/4, though I just manually enabled Fission and WebRender and didn't use the full prefs. Tyson, would it be possible to get bugmon to bisect a fix or something? Thanks.

Fission is enabled in the prefs, and the stack looks related to docshell stuff, so we probably want to track this for Fission.

I have a Pernosco session from the same test case but the stack is a bit different: https://pernos.co/debug/7FfXsdXZmrT-u-suMdWOkQ/index.html

Great! That stack has HasValidTransientUserGestureActivation at the top, so this might be same issue as bug 1685106.

see https://bugzilla.mozilla.org/show_bug.cgi?id=1685106#c2 for Nika's suggestion of the fix.

(Note: Patch for this is in bug 1685106)

:kmag, since this bug contains a bisection range, could you fill (if possible) the regressed_by field?
