Item display stops updating after collapsing and reopening tab

I have a tab called "Open Documents." When you click a button, it adds the name of a random document as a Navigation Item to the NavigationItemsCollection called "Items" of the tab. The tab header also gets updated with the total number of items in the Items collection.

This works fine, up until the point when you collapse the Open Documents tab. After this point, when you reopen it, the list of document names stops updating (but the header number still updates correctly).


STEPS:
1. I open the Navigation drawer, the Open Documents tab has no items under it, and it starts as collapsed, with the header "Open Documents (0)."
2. I click the "Add document" button. "Document 1" is added to the Items of the Open Documents tab, and the tab header now says "Open Documents (1)" and Document 1 is visible and clickable underneath it.
3. I click the "Add document" button again. "Document 2" is added to the Items of the Open Documents tab, and the tab header now says "Open Documents (2)" and both Document 1 and Document 2 are visible and clickable underneath it.
4. I click the "Open Documents (2)" tab to collapse it. The list of documents ("Document 1" and "Document 2" disappear from view, as expected.
5. I click the "Open Documents (2)" tab to expand it. The list of documents ("Document 1" and "Document 2" reappear underneath it, as expected.
6. I click the "Add document" button again. Unexpectedly, nothing is added to the visible list of items. It still only says "Document 1" and "Document 2", but the header does update to say "Open Documents (3)" despite this.


I checked in the debug and the Items list actually does have 3 items in the Items list in memory, but the list no longer will update visually on the front end. From this point on, it is no longer possible to change what items are shown to the user at all.

It seems like there is something happening in the background code when actively collapsing a tab that permanently stops updating the visual list of items for the tab for the rest of the time. Any help with this would be appreciated!

Note: I already tried using ItemsSource instead of Items, but that does not get updated either.
