Unfold from bus ignores inverting overbar.

Description

I was experimenting a bit with inverted bus members of a bus because of the now closed issue: #23521 (closed)

So I drew a small bus in 10.0.0-10.0.0~ubuntu24.04.1, release build, and it did not work properly (as expected). Then I downloaded a fresh testing appimage, opened the schematic which was created in V10.0.0 stable in it, and the unfold did not work either.

Steps to reproduce

  1. Open attached project.
  2. Use Unfold from bus to unfold "c".
  3. Overbar is missing.
