slider DOM uses margin to carve out space where it should probably use padding

As seen in this screenshot, the margin creates space that markers use. However, this means doing things like wrapping a slider in tooltip won't work as expected and this margin area won't trigger the tooltip.

After further inspection, this margin is added via inline styles and is not built-in to the component. Considering this is a non-issaue and can be closed.
