(Note: This isn't a "use case", it's a sample. A use case is a description 
of the reason why an author or user wants to do something.)

The "this.disabled=true" bit should have no effect on the submission 
(since the click has already occurred), and the "return true" part of the 
event handler should have no effect at all.

Thus, assuming the user only clicks once, the above should be equivalent 
to:

 <form action="javascript:alert('SUCCESS')">
  <input type="submit">
 </form>

Thus, Firefox is correct here, and WebKit and Opera are wrong. (I didn't 
test IE.)

I recommend filing bugs.
