Parent CSS scaling messes up the slider

[danisss9]

Bug
A bug I stumbled into is that the slider breaks (displays wrong) if the ngx-slider element or any of it's parents contain a CSS scaling transform rule (Eg : transform : scale(N) ; ).

Steps to replicate:

1. Create a parent to contain your slider and set the CSS rule transform:scale(2);.
2. Add an ngx-slider as a child to that parent.
3. Load the page and attempt to slide the slider.

@mdominiak2 A workaround seems to be setting the scale option as the opposite value of the scale set in css.

Example:

The calculation of the position/dimension of the slider would need to be reworked to really fix this.
