Rangeslider layout breaks upon form reset

[gabrielschulhof]

Steps to reproduce:

1. Visit http://jsbin.com/onibuc/350/
2. Type 50 into the lower end.
3. Click the "Reset" button

At this point the range slider layout breaks.

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?
