mouseover buggy in lte-ie8

[jonasboman]

Sometimes not showing tipsy on mouseover.
Using a forked version to be able to use on-methods.

    if (options.trigger != 'manual') {
        var eventIn  = options.trigger == 'hover' ? 'mouseenter' : 'focus',
            eventOut = options.trigger == 'hover' ? 'mouseleave' : 'blur';

        if(!this.live) {
            $(this.selector).bind(eventIn, enter).bind(eventOut, leave);
        } else {
            $(this.context).on(eventIn, this.selector, enter);
            $(this.context).on(eventOut, this.selector, leave);
        }
    }
