The color of the bar changes when hovering, see image:
Same happens when one uses other colors (.qa-form-tall-table{background:#ccc;}), each <tr> blinks when hovering over it.
Any clue ? Happened so in chrome...
Look to your CSS. This is not a bug that is a css parameter.
Change :hover styles by adding:
td#cke_top_content:hover{background:none!important}
I have this implemented for a while, check out: http://www.gute-mathe-fragen.de/ask
