Set release status flags based on info from the regressing bug 1831120

:ErichDonGubler, since you are the author of the regressor, bug 1831120, could you take a look?

For more information, please visit BugBot documentation.

I will investigate this as I find bandwidth to do so over the next couple of weeks. I suspect that the bug marked as the regressor is not actually the regressor (adding readonly attribute and additional spacing in IDL likely has nothing to do with this), but rather something else that has unblocked logic that was stopping this bug from being observed before.

FWIW, I dont get the crash on the latest Nightly.

The fix is bug 1856371.
:ErichDonGubler: feel free to close this bug

It repros here now: https://toji.github.io/webgpu-clustered-shading/

Comment 8

[Erich Gubler [:ErichDonGubler]]

Mayank: I'm confused. Is that the same crashing issue? Or does your other statement about closing this bug apply still?

Comment 9

[Mayank Bansal]

Lets close this bug as the original link doesnt crash anymore.

The crash signatures from the demo in comment #7 has changed now (maybe because of bug 1861751). The new signatures are captured in other bugs i have filed (bug 1863107).
