editing/execCommand/apply-inline-style-to-element-with-no-renderer-crash.html

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

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=editing%2FexecCommand%2Fapply-inline-style-to-element-with-no-renderer-crash.html&flavor=wk2&recent=false&architecture=arm64&style=release

TEXT DIFF:

+%uef5f%u9776%u63
 
 PASS apply-inline-style-to-element-with-no-renderer-crash

DIFF URL:

https://build.webkit.org/results/Apple-Ventura-Release-AppleSilicon-WK2-Tests/267196@main%20(4591)/editing/execCommand/apply-inline-style-to-element-with-no-renderer-crash-pretty-diff.html

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.

Comment 2 Ben Schwartz 2023-08-23 17:44:33 PDT

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.
