wgpu(web): assertion failed: wasm.is_instance_of::<T>() #4108
Description
Description
Possibly related to #3430?
I'm getting the same assertion failed: wasm.is_instance_of::<T>() error.
Apologies if I am missing something obvious, I am just trying to get the examples to run with no changes.
Repro steps
I've done my best to chain together the steps to reproduce it, you should be able to copy and paste the whole thing.
