 When pressing a scrollbar button, the expectation is that the screen will
 scroll until it reaches the end (top or bottom), or the button is
 released.

 Currently, both buttons (up or down) only advance the screen a very small
 amount (perhaps 1 pixel?) with each click, regardless of how long the
 button is held down.

 Dragging the scrollbar directly works fine.

 A second issue affects the appearance of the bottom button only.

 When this button is pressed, the arrow points down as expected. However,
 when the button is released and the cursor moved away, the arrow changes
 temporarily to the up position (see attached screenshot).

 It will stay in this position until either:
 - the cursor moves back over or clicks the button, in which case it will
 temporarily change back to the down position, or
 - another control (for example, a tooltip) takes the focus away from the
 button, in which case the arrow returns to the correct down position until
 the button is pressed again.
