swipe/pushState-cached-back-swipe.html

This test is a flaky timeout on wk2 on macOS, and specifically a flaky failure on release.

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=swipe%2FpushState-cached-back-swipe.html

TEXT DIFF:

 willEndSwipe
 didEndSwipe
 didRemoveSwipeSnapshot
+Failure. Because we're using the page cache, it shouldn't be long between the gesture completing and the snapshot being removed. (expected: 1000, actual: 1036)

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura (13.5, 22G74/arm64) using the following command:

run-webkit-tests --clobber-old-results --verbose --iterations 1000 --child-processes 100 -f --exit-after-n-failures 1 swipe/pushState-cached-back-swipe.html

REGRESSION:

I was unable to identify a regression point; however, the first failure appears to have occurred at 266683@main on macOS Monterey (x86_64) wk2 release.
