Interesting... So where would I go to report that?
I noticed that on the tutorial page for the mouse position the normal clicking works just fine for the pageX and pageY, so it must be something with the radio or label elements...

Indeed. In following the steps outlined in the link above (your responsibility) you would do well to isolate the most minimal test case that demonstrates the source and limits of the bug to help the person that receives your report. That would definitely including removing jQuery (ensuring it's not a jQuery bug) and perhaps determining on which elements and which events the bug occurs. Good luck!
So it appears that it when the label is clicked it triggers the 'click' event on the radio it is attached to, but does not pass the the coordinates of the original event to the radio event. Would that be an accurate description for the bug report?
