I was unable to reproduce this bug using arm64 and WebKit 2 on macOS Ventura. There is a possibly related bug with this test, see #259458 (or rdar://112801240).

The first instance of this flaky failure is at 258520@main.

It appears there may be an issue with the test itself. There was an edit made at 262519@main which intended to stop some of the flaky failures, but the issues persist.
