Title:
layerX/layerY wrong when mouse is over scrollbar
Status in Mozilla Firefox:
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.
