* Function: _unselect()

* Unselects the row from the form selection.
*
* Using regular js to update the class rather than this.removeClass('active')
* because the latter causes the browser to continuously call
* element.compareDocumentPosition, causing the browser to hang for long
* periods of time, especially on pages with lots of versions (e.g. 100+)
