TL;DR: This is me forcing Firefox to adhere to a new spec. revision early. It doesn't break in Chrome, but it will eventually. We need to fix web-sys as a downstream of the WebGPU IDL, which hasn't caught up yet, and then update WGPU. As a stopgap, we can backport just the deletion of maxInterStageComponents to WGPU's WebGPU backend.
