Description:
webanimations/accelerated-overlapping-transform-animations.html

The test was added at 230714@main and was a consistent failure briefly and then changed to a flaky image failure from the beginning of the test addition until today.

Reproduction steps:
I can reproduce this on 254266@main ToT.

Command:

Result: 
Unexpected flakiness: image-only failures (1)
