I had a similar problem with iframes, i solved it by making the item that
overlays the iframe (ie the canvas in your example) hidden until i wanted it to
receive events - if you can detect the mouse down on the iframe, perhaps you
can show the canvas so that you block all future events going to the iframe
until you detect mouse up (on the canvas) and re-hide the canvas
