This test fails but every once in a while it crashes with the above stacktrace. Here is an instance:

After fixing this please mark it as failing again.

[Claudio Saavedra]

This one also seems to crash only in GTK.

[Vitaly Dyackhov]

It crashes on WPE too. For example here: https://build.webkit.org/results/WPE-Linux-64-bit-Release-Tests/308097@main%20(25525)/results.html
