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

> [cropTo](https://w3c.github.io/mediacapture-region/#dom-browsercapturemediastreamtrack-cropto) already returns a promise, so querying "all" documents in the single viewport captured to identify the crop target, seems reasonable to me.

I think you mean "browsing context" where you said "viewport".
Do you have a reasonable limit on how many different documents could be embedded in that browsing context?

Cost to implementers is low priority, but non-zero. It's only a problem if accommodating implementers comes at a non-trivial cost to a higher-priority constituency. Does it?
