Multiple Annimations created by CSS transitions on iOS only

Very perplexing problem has arisen. The following webpage has a search input at the top that when focus a changes class attributes with a series of transition effects.

Some JQuery the binds the focus event and displays a tooltip.

On iOS the transition happens 3 times before it finally settles in focus and the tooltip never appears.

Here is the link in question

Any ideas why?

$('#header .search input').blur(function(){
     $('#header .results').removeClass('visible');
 });

    $('#search').focus(function(){
        if($(this).val() == '' || $(this).val() == $(this).attr('placeholder')){
     $('.suggestion').addClass('visible');
    }});
    $('#search').blur(function(){
      $('#header .suggestion').removeClass('visible');
