mirror() Creates ghost geometry

[jwagenet]

mirror(Plane.XY) creates ghost geometry in my example, which add volume to the part and render as selectable faces in ocp_vscode. As discussed on discord, this may be due to Open-Cascade-SAS/OCCT#26

Originally, this was to report where the combination of the previous fillet(ppp0110... , 8) and the mirror(Plane.XY) caused the entire operation to silently fail, but I was unable to reproduce in 0.9.0.

with BuildPart() as ppp0110:
    with BuildSketch(Plane.YZ) as s:
        with BuildLine() as l:
            JernArc((0, 0), (1, 0), 40, 90)
            Line((0, 46), (42, 46))
        make_hull()

    with BuildSketch(Plane.YZ) as s2:
        arc = s.edges().sort_by(Axis.Y)[:-1].sort_by(Axis.X)[1:]
        make_face(offset(arc, amount=8, side=Side.LEFT))
        Rectangle(46, 16, align=Align.MIN)
        add(s, mode=Mode.INTERSECT)

    extrude(s2.sketch, amount=100 / 2)
    fillet(ppp0110.faces().filter_by(Plane.XY).sort_by(Axis.Y)[0].edges().sort_by(Axis.Y)[-1], 8)
    revolve(ppp0110.faces().sort_by(Axis.X)[0], axis=Axis.Z, revolution_arc=90)
    mirror(about=Plane.YZ.offset(100 / 2))
    # This fails but it should work
    mirror(about=Plane.XZ)

show(ppp0110)
