On Windows, with OOP Webgle enabled, the testcase behaves very strangely :

1. Be on Windows
2. Make sure that OOP WebGl is enabled
3. Open the testcase in Nightly
4. Open a blank tab
5. Close the tab with the testcase

ER: The testcase tab closes
AR: The whole Browser window hangs for 15-20 seconds
The bug repros with both Hw-WR and Sw-WR, and with remote canvas enabled/disabled.

If you diable OOP WebGL by setting webgl.out-of-process= False, the hang doesnt repro.

Hi Kelsey, any updates on this bug?

No, sorry.

This was last reported by fuzzers running m-c 20231021-4124eee4f58c.

Ok, I think 20231021 would be WORKSFORME at this point?
