STR:

  1. Enable vertical tabs.
  2. Collapse the sidebar.
  3. Create a tab group.
  4. Make sure the tab group is open.

Expected:
Tab group label is horizontally centered in the sidebar like before.

Actual:
Tab group label is left-aligned when group is open and only becomes centered when group is closed.
