This test is a flaky failure on release builds of WK2 on arm64 machines.

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura 13.5 (22G74/arm64) running the test as follows:

run-webkit-tests --clobber-old-results --verbose --iterations 100 --child-processes 5 -f --exit-after-n-failures 1 editing/execCommand/apply-inline-style-to-element-with-no-renderer-crash.html

REGRESSION:

I was unable to bisect a regression point, as this error started before the oldest build results on the flakiness dashboard.

While I was unable to locate a regression point, it seems that the error got more common after 262728@main.

We have same test in following directory:

LayoutTests/imported/blink/editing/apply-inline-style-to-element-with-no-renderer-crash.html

Only difference is `editing` one is the latest from Blink ToT using testharness.
