It's a USVString in
https://w3c.github.io/presentation-api/#interface-presentationconnection, why
not here? You can change id too, because using USVString in this context
(readonly attribute) doesn't actually change the generated code)

Done.

     readonly attribute PresentationConnectionState state;
     [MeasureAs=PresentationConnectionClose] void close();
     [MeasureAs=PresentationConnectionTerminate] void terminate();
