C: VTreeviewT: buggood first issue

Description

Environment

Vuetify Version: 3.9.7 Vue Version: 3.5.13 OS: Linux undefined (current)

Steps to reproduce

  1. Type "TEST" into the search field
  2. The "John" node is not expanded

Expected Behavior

The tree should reveal its items in such a manner so that the found items are visible.

Actual Behavior

That doesn't happen. If the parent of the item being searched for is in its collapsed state before the search, it won't be expanded after.

Other comments

There's a similar issue: https://github.com/vuetifyjs/vuetify/issues/8497, but I don't see the mentioned props anymore in the documentation. It seems outdated.

Research direction
The issue involves VTreeview search/filter logic. The reproduction link provides a minimal example. Start by examining the VTreeview component source in packages/vuetify/src/components/VTreeview/. Look for the search method or computed properties that handle filtering and parent expansion. Check the linked similar issue #8497 for context. The goal is to ensure parent nodes expand when a child matches the search. Implement a fix that triggers expansion of parent nodes when a child is found via search.
