Nested notebook title displaying incorrectly

[streetwriters]

I have several notebooks with other notebooks nested inside.

Ex:
Reference

• Goals
• House
• Plans

Projects

• Thing A
• Thing B

When I click into a top level notebook, I see the bottom section of the navigation pane with the nested notebooks, and the title of that bottom section should match the main notebook name.

The first notebook I click into is titled correctly, ie. I click Projects and I see in the bottom pane:

Projects

• Thing A
• Thing B

The second or further notebook I click into will have the same title in the bottom section of the navigation pane as whatever notebook I clicked before. ie. after the above, I click on Reference, I see "Reference" at the top, but in the bottom pane:

Projects

• Goals
• House
• Plans

There seems to be some kind of stickiness / lag / re-used variable not being updated that could be causing this.

Possibly related to the fix for #6011 which moved the main notebook name into the title.
