I don't think we want to keep track of this. The behavior I think we want is:
   * Report a mixed content warning for a form action that is mixed content 
   * If the form action changes, even if it was initially mixed content, if it
changes to a *different* mixed content action, we should get another warning. (I
believe this is matches what happens if you try to change an img src
programatically to a new mixed content src, for example, but please verify).
   * Additionally, we want a mixed content warning when a submission is
attempted with a mixed content form action.

This variable prevents multiple warnings from occurring, even if the action is
changed to a new mixed content URL.

Agree. Removed!
