Title:
  layerX/layerY wrong when mouse is over scrollbar

Status in The Mozilla Firefox Browser:
  New
Status in “firefox” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: firefox

  When you have a DIV with scrollbars (overflow:scroll or overflow:auto)
  and connect a mouse handler like "onmousemove" to the div then
  event.layerX must contain the X mouse position relative to the upper
  left corner of the DIV. But this doesn't work in Firefox when the
  mouse is over the scrollbar. Firefox "wraps" the mouse position so it
  begins with X=0 at the left edge of the scrollbar. This is bad because
  in this way Javascript cannot determine if the mouse is over the
  scrollbar or if the mouse is on the left side of the DIV. Here is a
  demo:

  http://www.ailis.de/~k/permdata/20070903/scrollbar.html

  Move the mouse over the div and then move it to the right over the
  scrollbar and watch the displayed X coordinate wrapping from 186 to 1.
  Other browsers behave correctly. Tested it in IE, Safari, Konqueror
  and Opera. In my opinion the mouse events should not fire at all when
  the mouse pointer is over the scrollbar but my opinion is not
  important. So I think this should be fixed so Firefox behaves like all
  other browsers and don't "wrap" the mouse position.

  I also tested the current Firefox Nightly Build and the problem is
  still present there.
