Remove space before and after the slider bar

When a new Slideer is created, it is created inside a view and I can see an space before and after the slider (just set backgroundColor='red' on the style)

This is quite annoying in order to make it if with other components as the slider is always a bit smaller

Is this done in purpose? Can those spaces (padding or margin) be removed and make the bar use 100%

I tried setting the padding, margin, left, right to 0, but nothing...
