Tooltip text "SELECTED" appearing on a collapsed tab group when a tab inside it is active.

[vitaliso]

(Sorry in advance if this question has already been answered—I searched but couldn’t find a response.)

The issue is that, when a tab group is collapsed, a text label appears—specifically duplicated—indicating that one of the tabs within the group is currently active (selected). Once the group is expanded, this text disappears.

Question 1:
How can I remove this text in the collapsed state of a tab group?

Question 2:
Is it possible to indicate that a tab is active within a collapsed group using just a background color or border (similar to how active tabs outside groups are highlighted), instead of text?
