autohide show scrollbars when moving cursor inside the "scrolled" area

[fk1blow]

When autohide is active, the only way to show the scrollbars is to move the cursor outside, then move back in, or just scroll the content. Is there a way to have the scrollbars activated, when moving the cursor through the scrolling content(no scroll event, no going outside then back)?

Exactly the same question here. This auto hide behavior feels buggy.

You would expect the scrollbar to reshow when you move your mouse inside the scrolling content, but it doesn't. You need to move away from the scrolling area and then back inside... ?
