jQuery bug with Internet Explorer

[Ryan]

I came an error in Internet Explorer (I'm using 8, probably exists in all) when I was removing a class with animation.

I was trying to remove a class that contained a font-weight: bold declaration. When removing it using an animation effect it crashed in IE because I believe it was trying to animate the font-weight, which you cannot do it IE. It worked fine in FireFox.

Crashes with animation (IE only) $('.classWBold').removeClass('classWBold', 1500);

Fine without animation $('.classWBold').removeClass('classWBold');

Here is the error from IE:

There is no signature of .removeClass() that takes a second numeric argument.

Animation is documented to only animate numeric values.

This should be reopened or given a new duplicate as this occurs with a switchClass() when one or both of the classes change the font-weight.
