[UI Slider] min:0, max:1 doesn't fully work

Discovered this while talking on irc.

Using stock html/css the follow code only changes the value during drag and not durring clicking although the handle will move. The arrow keys will only work when moved to the right and not to the left.

$('#slider').slider({
	max: 1,
	min: 0,
	stepping: 1
});
