  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.
