Description Abrar Rahman Protyasha 2023-12-20 00:27:59 PST 
Async overflow scrolling was enabled by default for web platform tests in 270071@main. This WPT has been a consistent failure since then. Namely, this WPT now fails one check:

We should see if this a real bug or if the test needs to be written differently.
