We have detected a buggy behavior of draggable.js on our website with
Firefox. After digging a bit, we found that it might be related to
the "overflow-y: scroll" css property we use on the HTML element to
permanently show the vertical scrollbar.
Is it a jqueryui bug or a firefox bug ?
I've put online a modified copy of the draggable sample page to show
the buggy behavior :
Just reduce the size of your Firefox browser window to activate the
vertical scrollbar, scroll down a bit and start dragging.
You'll see the draggable objet jump up the page the same amount you've
scrolled the page down.
For the moment we have temporarily disabled the overflow-y:scroll css
Any help would be greatly appreciated.
