URL of deployed dev instance (used for testing):

Steps to test:

• open an annotation and go to segments tab
• focus a segment, remember where it is in the viewport
• close the containing group (must not be root group)
• click on segment in view port, open context menu and "focus segment in list"
• see that containing group is opened again and that segment is focused in list

other changes

• moreover, the root group in the segment tab is now always expanded

TODOs:

• fix that SwitcherIcon is still displayed

Issues:

• fixes Focus in segment list for segments in a collapsed group #7827
