Opened https://bevyengine.org/examples-webgpu/3d-rendering/decal/ on Firefox using WebGL2, on Chrome using WebGL2, and on Chrome using WebGPU
What went wrong
Nothing is rendered on WebGL2, the console says
Tex storage 2D multisample is not supported
On WebGPU, nothing is rendered until I move the mouse, at which point a rendered image flashes in for a split second:

The console tells me:
Binding doesn't exist in [BindGroupLayoutInternal "mesh_view_layout"].

decal/:1 WebGPU: too many warnings, no more warnings will be reported to the console for this GPUDevice.
Additional information
The 0.16 announcement post says:
Ultimately, forward decals offer broader hardware and driver support, while clustered decals are higher quality and don't require the creation of bounding geometry, improving performance. Currently clustered decals require bindless textures and thus don't support WebGL2, WebGPU, iOS and Mac targets. Forward decals are available on these targets.
So I would have expected this to work
