When you zoom the page in or out and double-click, the coordinates of the mouse click are reported incorrectly (as received by the javascript ondblclick handler). The incorrect mouse coordinates are reported as if the page was never zoomed at all. Single-clicks are reported correctly. I suspect something is wrong with the treatment of double-clicks in the framework because single-clicks are reported with correct coordinates.
