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

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@main. It is unclear as to whether this included the flaky failures on WK2 or just the reported constant GTK/WPE failures.
