The crash still happens occasionally, so updating the expectation to this below: # This also crashes with that skia issue, but since 303624@main it started having a text failure: webkit.org/b/286859 webrtc/captureCanvas-webrtc-with-video-scaling-adaptation.html [ Text Crash Pass ] 2171321 4 lmoura 2026-01-12 19:47:41 -0800 webrtc/video-vp8-videorange.html was assigned to this bug, but it's not crashing anymore since late December 2025. I've created bug305356 to track its current text failure. 2172727 5 philn 2026-01-17 03:24:41 -0800 *** This bug has been marked as a duplicate of bug 305356 ***
