[jQuery] if the handle of a ui.slider is clicked/dblclicked, the arrow keys can be used to move the handle - even if disabled.

As the subject states, if you click or double click on the handle of a
ui.slider, you can then use the arrows to move the handle, even if the
slider is disabled.  Also, if you use the up or down arrows, the
handle goes directly to the min value.  Is there a way to fix this?
