This problem is rarely occurring, and only appears to happen on Apple Silicon Macs. As such, I cannot reproduce these failures because I don't have access to said system type. Updated test expectations to Pass Failure here: https://trac.webkit.org/changeset/277299/webkit
[ Mac wk2 arm64 ] scrollingcoordinator/mac/fixed-backgrounds/fixed-background-in-overflow-in-iframe.html is a flaky failure Description: scrollingcoordinator/mac/fixed-backgrounds/fixed-background-in-overflow-in-iframe.html is now flaky failing with Monterey wk2 both release and debug. The first failure that I see on the dashboard was 03/28/22 at r292002 for Big Sur and 3/18/2022 at r291501 for Monterey debug and release. Neither appears relevant to causing this issue. This test seems to have been flaky since the start.

Still occurring on Monterey and Ventura.
Still occurring on Monterey and Ventura, but now a constant text failure with the same diff.
Correction: this is a constant text failure on all configurations of Monterey/Ventura with wk2.
This issue regressed to a constant failure at 267516@main, meaning this could be a re-baseline candidate.
