Re: [mediacapture-screen-share] Revisit: Let getDisplayMedia() influence the default type choice in the picker (#184)

It seems valuable to me to provide as precise as possible guidelines.
For instance, it is problematic to have capturing document be the opener of captured document.
Same-origin tabs is also problematic as noted by @alvestrand.

As of iframe communication, origin partitioning should help preventing example.com/evil.com iframe to communicate (through BroadcastChannel, IDB...) to example2.com/evil.com or to evil.com.
