[BugBot [:suhaib / :marco]]

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebGPU' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

It seems like this will happen any time the GPU hangs. Not much crash volume, and no steps to reproduce.
