Since the upgrade to version 46.0 using the new gtk3 interface, the
scrollbar has been exhibiting behavior inconsistent with previous
releases and other gtk apps on the system.

What I expected to happen:
 * Left-click below the scroller to evoke the page down function
 * Left-click above the scroller to evoke the page up function
 * Middle-click on the scrollbar to move the scroller to the cursor position

What happened instead:
 * Left-click moves the scroller to the cursor position
 * Middle-click on the scrollbar does not evoke any reaction
 * Right-clicking on the scrollbar evokes the page up/down function

This not only breaks expected behavior from the previous versions, it's
also inconsistent with scrollbar behavior on apps all across the board.
