Bug in implementation of mousemove event hander

I am a web developer, and I think there is a bug. If I create an element and add a mousemove event to it, the mousemove event should only fire when my mose moves over the element and is over the element. In Firefox, when no mouse button has been clicked, the mousemove events fire as expected, but when the mouse button is clicked on the element and then is moved off of the element, mousemove events continue to fire even though the mouse has left the element already, and this is not correct.

How do I file a bug report?
