Re: [mediacapture-region] What makes CropTarget special to require an asynchronous creation? (#17)

Does `MessagePort` remain bound in any way, or encode to some degree, the document in which it was originally instantiated? If I create a `MessagePort` in D1, then transfer it to D2, then to D3, will D3 know that this `MessagePort` is originally from D1?
