[Bug Report][3.6.9] VTreeview: Append/Prepend Slots not usable on parent nodes when activatable

[ConnorNoddin]

Environment

Vuetify Version: 3.6.9
Vue Version: 3.4.27
Browsers: Chrome 125.0.0.0
OS: Windows 10

Steps to reproduce

1. Create a VTreeview node.
2. Make the VTreeview activatable
3. Add a template using the append or prepend slots
4. In the template, insert a node

The node will not be visible in parent nodes on the tree. It will be visible for child nodes.

Expected Behavior

The nodes append and prepend to parent nodes in the tree.

Actual Behavior

The nodes do not append or prepend to parent nodes in the tree.

Other comments

Note, using selected instead of activatable works fine. Using neither selected nor activatable also works fine.

I have experienced the same problem: icons defined in the prepend slot are only visible in leaf nodes. This problem also appears in the example in the documentation. Version 3.6.7 works, 3.6.8 or newer doesn't.

I'm not sure the "activatable" keyword is available in 3.6.7? It appears when using that Vuetify version that the keyword has no effect

There was a select/activate regression in v3.6.7 #20024, it's been fixed, cy tests are also added to prevent it happens again.

Stay tuned for next release

@yuwu9145 After testing the new release, v3.6.11, the example that was originally posted still does not work with the icons.

What I meant specifically was activate/select regression, I quoted your "activatable" keyword in my previous comment. This issue is more about slot in ItemGroup. I am doing Treeview enhancement recently, it should be fixed soon

@yuwu9145 Awesome! I am most excited!

@yuwu9145 While you were working on your recent merge request, did you notice that the VTreeview search functionality doesn't appear to work? Maybe I am using it wrong https://vuetifyjs.com/en/components/treeview/#search-and-filter

[yuwu9145]

Didn't notice, let's track it in #19404

It's mostly working on dev branch, though "Case sensitive search" doesn't work
