Programatically opening a tooltip with out giving an event results in a javascript error.

[mdownes]

Hi,

I am receiving a javascript error when i try to programatically open a tooltip using the open() method.
I am not passing an event as a parameter as i have none.

The documentation states ......"event object is only necessary for delegated tooltips so the widget knows which element to show the tooltip for"

The problem is the following line where there is no check to see if the event exists:

if ( this.options.track && /^mouse/.test( event.originalEvent.type ) ) {

Please review the following test case:

Kind Regards,
