1218847 - Assertion failure: outputTrack->GetEnd() == GraphTimeToStreamTimeWithBlocking(interval.mStart) (Samples missing)

Status: NEW

(Core :: WebRTC, defect, P3)

Description

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

STR: See Bug 1193075 comment 32.

Basically, unless I explicitly stop a tab screensharing stream, I get this assert when I close the page or navigate away.
