Vertical tab scrollbars ignore input

Description of the issue:
When vertical tabs and the scrollbar option are enabled the scrollbar is displayed (without up and down arrows, if applicable), however it does not respond to mouse input (hover, click drag). If ctrl+tab is used the scrollbar position will update accordingly. If the mouse is hovered over the scrollbar it is recognised as having hovered over the tab stacked underneath instead

How can this issue be reproduced?

  1. Enable vertical tabs
  2. Enable Scrollbar for vertical tabs
  3. Open sufficient tabs to require the use of the scrollbar to navigate

Expected result:

Scrollbar responds to mouse input.
