[Diego De La Toba]

css3/filters/backdrop/backdrop-filter-with-reflection.html is a constant crash on MacOS WK1 Sequoia-TahoeA.


HISTORY:
https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&test=compositing%2Freflections%2Fdirect-image-object-fit-reflected.html&test=css3%2Ffilters%2Fbackdrop%2Fbackdrop-filter-with-reflection.html&test=http%2Ftests%2Ffetch%2Fkeepalive-fetch-2.html


BUILD URL:

REPRODUCTION: 
Reproduced on macOS Tahoe with the following:

I am going to mark expectations as pass fail while this pends investigation.

Crash log

I've extricated the crash log from the failing test run.

[Abrar Rahman Protyasha]

Indeed, crashing under `WebCore::PlatformCALayerCocoa::shadowPath()` suggests this is a direct fallout from 305692@main.

This is also the same crash seen in https://bugs.webkit.org/show_bug.cgi?id=306894.
