I'm not totally sure about this feature, but maybe we can abstract from the specific behavior:

Summary
From Chrome 140 onwards, calling
GPUAdapter.requestDevice()multiple times on the same adapter causes the returned promise to reject. This is because the adapter is consumed by the first call. See https://developer.chrome.com/blog/new-in-webgpu-140#device_requests_consume_adapter.Previously, you could call
GPUAdapter.requestDevice()multiple times on the same adapter, but multiple calls would result in lost devices.This PR tries to capture the old and new behavior in a single data point, rather than adding multiple data points for a behavior change, which would be rather odd. Let me know if you think this works, or if we should do it a different way.
