Description Bri Harris 2023-01-26 16:51:15 PST

imported/w3c/web-platform-tests/webcodecs/videoFrame-texImage.any.worker.html 

is a constant text only failure on iOS. 

HISTORY:
https://results.webkit.org/?suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fwebcodecs%2FvideoFrame-texImage.any.worker.html


The interesting part about this failure is that the test results differ depending on if the test is run on Apple Silicon or Intel.

I was able to reproduce the text failure initially as follows on iOS Release and Debug ToT:
run-webkit-test --iOS-simulator imported/w3c/web-platform-tests/webcodecs/videoFrame-texImage.any.worker.html
