Research direction

Start by locating the navigation expanding visitor and its handling of set operations. Verify the behavior when both operands are identical, then update the relevant logic so navigation rewriting does not terminate in that case and confirm the existing query behavior remains correct.

Description

area-query

The navigation expanding visitor currently treats set operations as terminating, but we should not be doing this when both operands are identical.
