Rendering a compound made of multiple object types ignores labels and colors

[dalibor-frivaldsky]

The code below creates three compounds with build123d, but only the last two display the specified labels and colors of the shown objects. When combining multiple types of objects (e.g. Parts and Sketches), as is being done in the first compound, none of these properties are taken into account.

with BuildPart() as box:
    Box(10, 10, 10)

with BuildSketch() as rectangle:
    Rectangle(10, 10)

compound_multiple = Compound(
    label='Multiple object types',
    children=[
        Compound(box.part, label='Box', color=Color('red')),
        Compound(Pos(20, 0, 0) * rectangle.sketch, label='Rectangle', color=Color('green'))
    ]
)

with BuildPart() as box2:
    Box(10, 10, 10)

compound_parts_only = Compound(
    label='Boxes only',
    children=[
        Compound(box.part, label='Box', color=Color('red')),
        Compound(Pos(20, 0, 0) * box2.part, label='Box 2', color=Color('blue'))
    ]
)

with BuildSketch() as rectangle2:
    Rectangle(10, 10)

compound_sketches_only = Compound(
    label='Rectangle only',
    children=[
        Compound(rectangle.sketch, label='Rectangle', color=Color('green')),
        Compound(Pos(20, 0, 0) * rectangle2.sketch, label='Rectangle 2', color=Color('yellow'))
    ]
)

show(compound_multiple)

show(compound_parts_only)

show(compound_sketches_only)
