Tabs shoud NOT use togleClass() for .ui-state-hover

Currently tabs (from latest SVN) binds the following function to mouseover and mouseout:

var handleState = function(state, el) {

if (el.is(':not(.ui-state-disabled)')) {

el.toggleClass('ui-state-' + state);

}

};

This breaks easily. I have no deterministing way to reproduce it, but very often after some playing with tabs, the state for a tab becomes "switched" incorrectly - i.e. it has -hover when the mouse is away, and no -hover when it's on top of it. This has happened to me many times, with various browsers.

Solution: Tabs should use addClass() and removeClass() for the appropriate event, not toggleClass().

The same thing probably applies for ui-state-focus as well.
