Re: [mediacapture-region] [QUESTION] How to pass CropTarget to chrome extension service worker? (#75)

For the record, my understanding is that messages passed between browser extension contexts (content script and service workers) must be "JSON-ifiable" objects ([source](

Even though CropTarget is [serializable](, it's not enough to get it to work in browser extensions.

I think this is one more use case for which proposes to use a unique identifier instead of an opaque wrapper.
