UPDATE: Since it was apparently just trying to find a row to focus, I added a check to see if the object was null. I wrapped
the call like this.
 
function(){if(l._current)l._current.closest("table")[0].focus();}



Seems to be working now for both a single row on the grid or multiple rows. Hope this gets fixed in a future release.
