• Component: New Bugs
• Status: RESOLVED FIXED

[Karl Rackler]

Description:
imported/w3c/web-platform-tests/webrtc/RTCRtpSender-replaceTrack.https.html

The first failure that I saw on the dashboard was 5/6/2022 at r293885, and the dashboard shows passing on r293882.  Between r293883 and r293885 probably introduced the consistent failure. 

REPRODUCTION STEPS
I can reproduce this on r293885, but repro against all earlier commits are also failures which is different from the dashboard history.

Command: 
run-webkit-tests --root 293885 --ios-simulator --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 --no-retry imported/w3c/web-platform-tests/webrtc/RTCRtpSender-replaceTrack.https.html

The test history does indeed suggest that this started with r293885 / 250343@main, and that is the only WebRTC related commit in the range.
