List items should have role 'listitem'

[isidorn]

Currently the list sets the role of each item to be treeitem here
This should only be done for the Tree, not for the list. List should use listitem. More details here

Tree that actually uses the list should probably pass the role treeitem as the getRole to the list it extends from.
@joaomoreno if you are busy let me know and I can look into this.

We should also verify this nicely works with NVDA, since it is part of aria 1.1 spec.

[joaomoreno]

Sure, PR would be great.

[isidorn]

Sure. Assigning to this milestone and if I do not find time might get pushed out.

To verify

1. Windows, turn on NVDA
2. Open suggest box -> make sure that the suggestions do not have "Level 1" read ath the end
3. Open explorer -> make sure the items have appropriate Level read at the end
