ok, it seems that when the reset occurs, the css for "ui-slider-bg" is wrong. it gets a width of the start of the slider to the second handle, drawn from the first handle, instead of getting the width from the first handle to the second handle, drawn from the first handle. (so on reset, we need to get the value of the width by doing value2 - value1 instead of just value2)
Is it that _updateHighlight(); is not called upon reset?
