MYFACES-4606 Causes Multiple Events To Queue

Easier to demonstrate via the attached app (note that ajax tags have a blur event).

1) Deploy application with  MYFACES-4606 applied.
2) Visit index.xhtml
3) Click down on the first button (don't let go)
4  Move the cursor elsewhere and then let the click go.
5) Click anywhere on the page to trigger the blur event (unfocus the button).
6)  Repeat with the second button

With the second button, both the listener and confirm actions to occur. Even though, the button wasn't actually clicked.

In my view, only the listener event should occur, not the confirm actions. However, by adding the issuing element to the request, JSF thinks the button was clicked after all.

In summary:
Before 4606:
Button 1:
  nothing called
Button 2:
  listener called

With 4606:
Button 1:
  confirm called
Button 2:
  listener called 
  confirm called 

The activate action check is here:
https://github.com/apache/myfaces/blob/2.3.x/shared/src/main/java/org/apache/myfaces/shared/renderkit/html/HtmlButtonRendererBase.java#L65

The "isSubmitted" method return true for paramMap.containsKey(clientId) which is what the 4606 fix did (add the client id).

This there a way to keep the older behavior for this scenario (pre-4606)?

Additionally, I've seen the multiple invocations for the listener / confirm, but I can't pin point the problem (could be some other button click combination).
