I show a div with a higher z-index value than some others using

1. $('it').show('explode', {}, 'slow');

and during the explode animation it appears below the lower z-index elements when using Firefox but on top as expected using IE 8

I tried using other effects such as slide but that messed up dragging for the shown element (i.e. once shown it couldnt be dragged, with explode draggable works as expected)

Originally I had just been using show('fast') but that messes up the transparency during the animation on IE (see http://dev.jquery.com/ticket/5946 if curious)

I am using 1.7.2 (I tried using 1.8rc1 and the slide effect to see if the problem was fixed but the element never even appeared. Either its really broken or more likely the API changed)
