fullWidth prop for Slider does not work in v 1.11.3

[roberta-racco]

Adding the Slider component:

<Slider
  fullWidth
  name={`slider-name`}
  min={0}
  max={100} 
  minLabel="%"
  maxLabel="%"
  disabled={!checkValue}
  value={value}
 />

even if i remove or add the fullWidth prop the slider is rendered always small
