Remove "responsible document" concept
Browse files Browse the repository at this point in the history 
It was confusing to have this as a generic on environment settings objects, since it only applied to window environment settings objects. Instead, specifications should get the Window object's associated Document directly, if necessary by looking at the settings object's global object (which will, in some cases, be a Window object).

Closes #4335.
