Scrollbars are an interface that represent and allow to control which
part of an element is rendered. The `-ms-scrollbar-*` properties would
control the actual scrollbar, but you generally would not refer to some
UI control in order to manipulate concepts they are an interface to.
You would not have a property `volume-slider: 100%` for `volume: 100%`.
And if this was to work with overflow:hidden, say because you have some
touch UI or because you don't actually want the user to scroll, then it
becomes confusing to set `scrollbar-*` properties, since there is none.
And which scrollbar anyway, considering there can be more than one.
