Tree view highlights multiple items when collection aliases partially match

[andrejd22]

Describe the bug
If one collection alias partially matches another (e.g., comments and commentsGroup), selecting the second one results in both items appearing active in the repositories tree.

Steps To Reproduce
Steps to reproduce the behavior:

1. Set two collection aliases: e.g., comments and commentsGroup.
2. Navigate to the repositories tree in the UI.
3. Click on the collection with the alias commentsGroup.
4. Both comments and commentsGroup tree nodes become highlighted as active.

Expected behavior
Only the selected collection's tree item should be marked as active.

Hi @andrejd22 ,

This issue has been raised to the CMS team and fixed with this PR on v16 of Umbraco.

We have started working a v16 for UI Builder, and I would recommend upgrading to v16 once we have an RC released.

Thanks,
Adrian
