Re: [csswg-drafts] [css-scoping] Allow elements to expose a subset of their shadow tree, which can then be styled with regular CSS (#10939)

@sorvell if we co-opt parts we’ll have to decide on whether or not putting the part in the “exposed shadow tree” list adds the element the part is on and it’s children, or only its children. 

seems like if it’s the element with the ::part, then we might also need to decide if adding that part to
the “exposed tree” list removes it from the parts list. if it’s exposed via the exposed tree AND via ::part styles, that seems a) redundant and b) ripe for style clashes. 

if it’s only the children then that might be a little counterintuitive for what `part=` does today, which applies to the element itself (but not its children ha)
