Rendering fails in Safari with WebGPU enabled, purple screen

[valentinegb]

With WebGPU disabled, which it is in Safari by default, all you get is a white screen, which is expected. However with WebGPU enabled it's not much better. The menu appears, the game seems load (or it did before I reloaded the page and started recording), but the screen is just purple.

~~Sorry for the bad video quality, I realized after recording that for some reason OBS reset all of its settings...?~~
