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.
