With jQuery alone, everything works fine. However jQuery UI 1.9.2 css hook seems to force lookup color of parent element and set it as background color instead of transparent.
In IE9, the color is set to rgba(0, 0, 0, 0) but in IE8/7 the color is set to rgb(255,0,0).
Also I was trying to post a bug report but trac seems to keep giving me OperationalError: (2006, 'MySQL server has gone away') error...
