Expected result

In Safari, the demo loads and reports about 45 Gflops on my MacBook Pro.

Hacker News comments say Chrome throws the same error and that this problem is "Safari's WSL API, which doesn't work on the other browsers. There's a bit of a debate about the API (Spir-V vs WSL/WHSL)":

Should this bug be resolved as invalid?

Correct. Safari hasn't updated its WebGPU implementation in a year, we don't expect it to be compatible at this point. Hopefully, they'll catch up.
