keyboard focus on togglebutton
It appears to me that when using button() to create a toggle button from a checkbox+label (as shown on
http://jqueryui.com/demos/button/#checkbox ), it doesn't add ui-state-focus when you tab to it the way it does with buttons created from input, button, or anchor elements.
The togglebutton IS keyboard-accessible, but without any way to style the focus it's not obvious to the ordinary keyboard-navigating user. Is there an option or configuration that I'm missing here, or should I try to add this myself?
