RE: Determining what prototype should be used for an object

Very interesting...

This is the global environment it initially got its prototype from, except in some cases for nodes when adoptNode is involved.

Just to sharpen the discussion, it would help to give one example of each...

Honestly the WebIDL answer sounds pretty reasonable to me, so I am interested in where ES mismatches.
