fadeIn() corrupts css filter propery on IE8 if element has a DXImageTransform.Aplha

Description

In IE8 (and only IE8 as far as I can tell) when calling fadeIn() on an element which has a progid:DXImageTransform.Microsoft.Alpha(Opacity=85) filter set through a stylesheet, that filter ends up as DXImageTransform.Microsoft.

After some testing I found that somewhere during the fadeIn() the set function of jQuery.cssHooks.opacity is called with an empty value for opacity, which causes the opacity variable in there to be empty and thus "stripping" the end of the filter on the last line of that function.

I found this on jQuery 1.7.2, but a quick check confirmed that it's still present in 1.8.0

Test case that's easier to see: http://jsfiddle.net/sk434/4/

However, quirksmode recommends this order to get things right: http://www.quirksmode.org/css/opacity.html

Is this what you expected? http://jsfiddle.net/sk434/6/

Yes, that's the behaviour I was expecting.
