slidestop event not firing when mouse outside slider

jQuery version: 1.7.1

• OS X 10.7.2 / Chrome 16

Instructions to reproduce:

Create a slider element and bind something discernible to the slidestop event (e.g an alert).

Correctly trigger the slidestop event by moving the slider with the mouse above the slider.

Incorrectly fail to trigger the slidestop event by clicking the handle, dragging, then moving the mouse outside of the slider handle (e.g if it's a vertical orientation slider, move the mouse horizontally) - you can still move the mouse in the direction of the slider and the slider responds, however, releasing the mouse at this point fails to trigger the slidestop handler.

This is problematic to me for several reasons:

• My slider is very narrow (a few px), but the handle is much wider (15px) - so even with the mouse over the handle, because it's outside the slider bar itself, it fails to trigger the handler
• I have other events bound in my page, which are put on hold because the slider's sliding. If the slidestop doesn't trigger, my page gets frozen in an undesirable state.

For now I've hacked around it by adding a boolean variable which tracks when the slider's in use, which is unset with $('BODY').mouseup
