Bug Description

[ Test case ]

Comobobox lists extenders use invalid arrows
 1. Both at the top and at the bottom, the arrow (triangle) points downwards.
 2. Colors of sensitive and insensitive arrows are swapped.

[ Test case ]

 1. Open gnome-terminal, in menu goes to:
    Edit -> Profile Preferences -> Compatibility -> Encoding
 2. The arrow at the top should point upwards
 3. Tha arrow at the bottom should point downwards
 4. Arrows should be visible only when there's actually something
    to scroll up or down.

[ Regression potential ]

Arrows aren't shown as expected in menus or combo-box


Open a combobox with plenty of entries. (Example: gnome-terminal -> Edit -> Profile Preferences -> Compatibility -> Encoding)

Notice two bugs:

1. Both at the top and at the bottom, the arrow (triangle) points downwards.

Expected: At the top, the arrow should point upwards.

2. Colors of sensitive and insensitive arrows are swapped. The arrow is black if you cannot scroll in that direction, gray if hovering starts to scroll.

Expected: It should be black if you can scroll in that direction by hovering, and gray if you cannot.

Adwaita doesn't suffer from either of these issues.
