Provide a general summary of the issue here
Summary
In all Tree variants, elements on level 1 are always announced as “1 of x level 1” by screen readers, regardless of their actual position.
Problem
The real position of each root-level item is not conveyed.
Likely cause: aria-posinset is always set to 1 for all root elements.
Proposed Fix
👨💻 Investigate and ensure that aria-posinset correctly reflects the actual index of each level 1 item in the tree.
