Description:
webrtc/canvas-to-peer-connection.html

The first failure I saw on the dashboard was on 5/6/2022 at r293885.  r293885 removed usage of PixelBufferConformer in RealtimeOutgoingVideoSourceCocoa so that possibly introduced the consistent failure on macOS X86_64 wk2. 

REPRODUCTION STEPS
I can reproduce this on r293885.

Command: 
run-webkit-tests --root 293885 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 -f --no-retry webrtc/canvas-to-peer-connection.html

Result: 
Regressions: Unexpected text-only failures (1)
  webrtc/canvas-to-peer-connection.html [ Failure ]

I have marked this test as a consistent failure while this issue is investigated.
