The algorithm "create a new WebGPU object" says:

6. Set object.label to descriptor.label.

However, descriptor.label is an optional member of the GPUObjectDescriptorBase dictionary type, whereas the label attribute of GPUObjectBase is declared:

attribute USVString label;

which doesn't admit null as a value.

When the label is omitted from the descriptor, it's not clear what we want to have happen:

• If USVString is the type we want, then I guess it'd have to be set to the empty string.

• But maybe we want USVString?, and an omitted label dictionary member results in a null label.
