This is kind of a confusing bug, but here's the gist of it:

1. The code in StructuredCloneData.h makes it look like there's a move assignment operator. However, you can't actually use it, because the default move assignment operator doesn't apply to this class. I think we should implement a move assignment operator ourselves that works. I don't see any reason why we couldn't.

2. The Copy method of StructuredCloneData should probably assert !mInitialized. Since it appends to things like PortIdentifiers(), it will add to the existing data rather than replacing it.
