 This test performs an animation and then dynamically loads a new stylesheet (which is empty). It should start animating after a 100ms delay and then stop halfway through the animation at which point we see if it is at the correct position. The loading of the stylesheet should not prevent the animation from running.

Comment 11 Fujii Hironori 2023-11-06 16:52:28 PST
It's reproducible with Windows debug on my PC.

> python Tools/Scripts/run-webkit-tests --debug --no-build animations/dynamic-stylesheet-loading.html --iter=100 -v --no-retry --expect-pass -f

But, not reproducible with Mac debug WK1 and WK2 on my Mac.

> Tools/Scripts/run-webkit-tests --debug --no-build animations/dynamic-stylesheet-loading.html --iter=1000 --no-retry --expect-pass -f
