Description Grant Gayed CLA 2015-01-20 12:30:28 EST 
Our uncaught error logging indicates that toolTip div may be null in the following snippet in tooltip.js:

var tooltipDiv = this._tooltipDiv, tooltipContents = this._tooltipContents;
tooltipDiv.style.left = tooltipDiv.style.right = tooltipDiv.style.width = tooltipDiv.style.height =  tooltipContents.style.width = tooltipContents.style.height = "auto"; //$NON-NLS-0$

...which causes a null reference on the second line at "tooltipDiv.style".  This has happened 7x in the last two days.

Fixed in master

If the hover is destroyed before the call to show we shouldn't be trying to open the tooltip.
