See url, inside the black bordered box inside the iframes, just make some swipe movements.

Notice how the page moves inside Fennec. That should not be happening.

Also pinch zoom gestures shouldn't have any effect other than that black lines are drawn inside the black bordered box.

Tested on the Samsung Galaxy Nexus.

This works at least in a 2012-03-15 trunk build.

Also, notice how drawing lines in the top iframe are not bound by the iframe box, which it should. But this is a different bug. I filed bug 747791 for that.

To explain the problem, we weren't notifing java of the listeners, so it allowed panning.

With our new touch handler, once we've started giving events to the touch handler we don't give the page another chance to stop prevent panning. We did that on purpose because trying to start and stop panning after the page responds leads to confusing situations for the user (and our backend)

I can r+ this, I suspected it was something like this but hadn't started looking for the relevant line of code yet :)
