[whatwg] Should <video controls> generate click events?

In a discussion about a "click to play/pause" feature for Opera on  
Android, the issue of click event handlers came up.[1] The problem is that  
pages can do things like this:

v.onclick = function() {
   if (v.paused) {
     v.play();
   } else {
     v.pause();
   }
   // no preventDefault()
}

I created a demo [2] and it is indeed the case that this makes <video  
controls> unusable in both Presto and Chromium based browsers. Simon  
Pieters has brought this up before, but the spec wasn't changed at that  
point.[3]

While my demo may be on the hypothetical side, we do want users to be able  
to bring up the native controls via a context menu and be able to use them  
regardless of what the page does in its event handlers. So, I request that  
the spec be explicit that interacting with the video controls does not  
cause the normal script-visible events to be fired.
