test: the restored wall does not move after it paints

One rail column in the whole of run 2's capture — matched as the full
rail glyph (CUP, reverse video, one space, reset), because a label bar
starts with the same CUP+SGR at its pane's own left column and the
looser rail_cols prefix reads the right pane's bar as a rail.
