[FIXED]Hidden scroll bar in mega menu

[Arakash]

This, probably isn't really a bug as such but this is probably the most appropriate place to put this anyway.
A small error with the UI that drives me up the wall (image attached).

Yes, this also annoys the hell out of me, along with the thing where once you click apply, it moves you to the top of the list, which forces you to scroll down for every model.

If i could suggest one thing, its that you try to make the thread title reflect the problem. Perhaps "Hidden scroll bar in mega menu"?
