Closing PR #40982 and removing active labels. 2113507 3 graouts 2025-04-28 05:36:50 -0700 Looking at https://results.webkit.org/?suite=layout-tests&test=fast%2Fanimation%2Frequest-animation-frame-throttling-lowPowerMode.html, it appears that this test is reliably failing only on the "Sequoia D site-isolation Release on Macmini9,1 with arm64" bot, so perhaps this failure is specific to site isolation somehow? 2113508 4 graouts 2025-04-28 05:37:20 -0700 Moving to the Layout & Rendering component since this is about requestAnimationFrame() and not animations.
