FYI: Looks like these tests started running on the Android bots recently:
https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=webkit_layout_tests&tests=animations%2Fanimation-shorthand-overriding.html

The failure seems to indicate that the GPU process failed to initialize:

[26716:26732:0815/173724.601554:FATAL:gpu_data_manager_impl_private.cc(866)] GPU process isn't usable. Goodbye.

In all of these failures it looks to me like a large list of tests (animation and non animation) are failing for the same reason. I'm moving component to GPU pending a reason to suspect the failures are specifically related to blink animations.

Is the crash only happening on this bot?

This appears to have been resolved on the bots. My guess (looking at the CLs from the initial regression) is that this was due to https://chromium-review.googlesource.com/c/chromium/src/+/1161601 which has since been reverted here: https://chromium-review.googlesource.com/c/chromium/src/+/1181585

Unfortunately, a second issue seems to have broken the tests in the meantime, making it tricky to confirm the fix. However, everything is green now.

We should probably just restore the tests disabled in #1.
