slider styling looks different in Edge

[becky-gilbert]

In the v6.2 *-slider-response plugins, custom CSS is used for slider tracks/thumbs to fix the positioning of slider positions and labels, but the styling looks different in Edge vs other browsers. In Edge, it seems like the thumb can only extend slightly above/below the track, otherwise it gets cut off. So compared to the styling in other browsers, in Edge the thumb has to be shorter and/or the track has to be taller. See here.
