Description Grant Gayed

The following exceptions were recorded by our analytics 6 total times in the last week, in Chrome:

Uncaught TypeError: Cannot read property 'ownerDocument' of null (git-repository.js: 3220, 63)
Uncaught TypeError: Cannot read property 'ownerDocument' of null (edit.js: 3406, 63)


I don't have steps to reproduce these problems.  They both seem to point to the line in tooltip.js:


newTooltipContents = util.createElement(this._tooltipDiv.ownerDocument, "div");

I don't see a way to reproduce this either, as the tooltipDiv is created when the constructor for tooltip.js is run.  Perhaps there is some order of operations where the destroy method can be called before a mouse hover completes (as it uses a window timeout).

Fixed in master with an existence check.
