COMMIT TO FIX:
This is happening because we aren't honoring the class specific property
slider-width (we have it as slider_width), and we aren't giving
precedence to class specific properties before style properties. Both of
these issues have been fixed in 1.5
This bug is not an issue for 1.5 as 4632193 and 4795413 fixed it.
