From the `about:support` dump in comment 7, OP is apparently reproducing on a graphics device with PCI vendor ID 0x8086 (Intel) and device ID (0x9BC4). This appears to be an [Intel Comet Lake GT2](https://www.techpowerup.com/gpu-specs/intel-comet-lake-gt2.g925), which uses Intel HD Graphics 630.

Based on the WebGL info in that same `about:support` dump, it seems that WebGPU's backend is actually foregoing selection of an NVIDIA device. This appears to be because we are requesting low-power devices from WGPU when `GPURequestDeviceOptions.powerPreference` is omitted; I've filed bug 1841840 to capture it as a separate issue from this one.
