Bug with ability to exceed min/max threshold

[ghost]

If you click on the value in the middle of the knob and use your up/right or down/left keys to increment or decrement the value, you are not limited by the minimum or maximum values of the knob.

For instance, on a knob which is ordinarily in the range [0,100], you are able to go way past 0 to -1 and beyond. Likewise you can exceed 100 by incrementing forever.

This issue exists also when you have explicitly set a data-min or data-max.
