> Both Webkit and Firefox based browser are honoring mouse events inside
> iframe. However, if a widget is in a dragging event, and mouse cursor pass
> through another iframe. Mouse event get captured by the background iframe
> and cause the dragging widget to stall. One trick was to overlay an
> invisible DIV with higher zIndex to prevent the background iframe from
> capturing mouse dragging event of the transitioning widget. This was
> implemented several years back for firefox only, but it looks like the same
> trick needs to apply to all modern day browser. This JIRA is to remove the
> firefox specific check and always overlay the invisible iframe when mouse is
> dragging over another iframe.
