[ Viz Settings ] Default values not reflected by UI elements

Created by: S4K4YUME

For some form-components it works as intended. I.e. the checkbox nicely follows the default_value it is given.

The same does not hold for the sliderField.

The image below shows 4 sliders, min: 0, max: 255. Two of them correctly show 0, the other two are halfway when they are given the max default_value of 255.

Upon further investigation it appears that any positive value other than zero makes the slider move towards the center position. This feels like true/false behaviour.

Perhaps the options within addSliderField should be tweaked?
