​

This is a regression.
Bisection was not accurate as the site doesnt load sometimes. But possibly the regressor is bug 1919404
Demo runs on Chrome release.

Discussion upstream: https://github.com/gfx-rs/wgpu/issues/6290#issuecomment-2395263426

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.

Just filed a PR upstream to fix it, which I've verified as working locally: fornwall/wgpu-game-of-life#1
