I propose to change the specification to remove any elements that are no longer associated with the form from the past names map:
It's strange for elements to linger around forever in the past names map after the element get associated with a new form element. Since IE didn't support form attribute for a long time (or maybe still hasn't?), I don't think there is any compatibility concern.
The change makes the elements associated with the form element more consistent and easier to reason about. We can make form[x].form === form an invariant for every x such that form[x] is a form control element.
