nit: you need a subject in this sentence and need to end it with a period, e.g.:

  If this function is defined and returns true, selectstart events will be
allowed. Otherwise, the default action will be prevented.

something like that...

+ * @param {function(Event):boolean=} opt_allowDragStart If this funcion is
+ *    defined and returns true, will allow the DragStart event to be processed
