If a glyph contains both regular paths and components, and the component does not have anchors, it is not possible to set that component to have automatic alignment. However, if checking such a component for automatic alignment via component.automaticAlignment it will return True, even when it is not (and can not be) auto aligned. It’s possible I’m misunderstanding the intention of automaticAlignment though.
That property means that the component would align if it was enabled for that layer.
