http/wpt/cache-storage/cache-quota-after-restart.any.html

This test is a flaky failure on macOS and iOS, constant failure on x86 (GTK/WPE/Wayland).

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=http%2Fwpt%2Fcache-storage%2Fcache-quota-after-restart.any.html

TEXT DIFF:

-CONSOLE MESSAGE: Cache API operation failed: Quota exceeded
 CONSOLE MESSAGE: Cache API operation failed: Quota exceeded

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura ToT running the test as follows:

run-webkit-tests --iterations 500 --verbose http/wpt/cache-storage/cache-quota-after-restart.any.html

REGRESSION:

This test has been a flaky/constant failure on the reported platforms as far back in history as the flakiness dashboard extends. From a previous bug report (bug #196197), I was able to identify a potential regression point at the time of test introduction at 210340 at main. It is unclear as to whether this included the flaky failures on WK2 or just the reported constant GTK/WPE failures.
