inspector/canvas/shaderProgram-add-remove-webgl2.html

Is flaky failing and timing out on all macOS platforms.

This was reported 4 years ago https://bugs.webkit.org/show_bug.cgi?id=179827 but seems like it's never fixed. There is also a bug about crash https://bugs.webkit.org/show_bug.cgi?id=206718 that doesn't seem to have been fixed and can still be seen on Big Sur wk2 debug.
