           Summary: InvalidAccessError usage is questionable; use
                    TypeError instead?

"If keySystem is an empty string, return a promise rejected with a new
DOMException whose name is InvalidAccessError.

If supportedConfigurations was provided and is empty, return a promise rejected
with a new DOMException whose name is InvalidAccessError."

In general TypeErrors are preferred for invalid arguments. I think in general
the existence of InvalidAccessError is a mistake from the days before it was
realized that IDL was not a language-agnostic layer. (I will file a WebIDL bug
to discuss.)

No big deal though.
