I just hit a fatal-assertion at shutdown after visiting https://www.msn.com/en-us/weather/forecast and clicking "hourly" and then quitting, in a debug build:

I happened to catch it in rr; I was trying to capture a different shutdown-crash but I caught this one instead. :)

I'm uploading the trace to pernosco and I'll share the link here when I've got it.

This was on a mozilla-central build with yesterday's tip (https://hg.mozilla.org/mozilla-central/rev/634515c4e099 ) plus the two relatively-small layout-specific patches on bug 1700474 (which are irrelevant to this assertion-failure, so I think we can consider this ~unmodified mozilla-central).

I think we fixed this recently.
