I'd leave it up to the UA.

The user should know that the element can be manipulated, because 
they've been prompted by
the author/style of the page, or are otherwise aware of their browser 
environment. click+drag, touch,
pen flicks, and all other modalities are at least, familiar to users, if 
not immediately apparent.

The goal here is to inform the UA that screen width/height is privileged,
and if possible, scroll indicators should be hidden when the element is 
not actively being
scrolled.
