Provide a way to add classes to a specific tree view item

[JohannesPertl]

Describe the feature in detail (code, mocks, or screenshots encouraged)

I'm using tree view items in a RecursiveTreeView for navigation and mark the current active one by applying bg-primary-active-token like this:

This is currently only possible with some hacks. A simpler way to access a specific tree-item-summary class would be nice.

What type of pull request would this be?

None

Provide relevant links or additional information.

This will ensure that we can see the full context of requests when the time comes to refactor and update this feature going forward.
