I have (what I think is) the same problem—in particular, when nesting an instance of an interactive component within another component (interactive or not), none of the hover interactions work.
- Page design (non-interactive component)
- List
- List items (interactive components)
No interactions
- List items (interactive components)
- Modal (non-interactive component, shown as an overlay)
- Buttons (interactive components) No interactions
- Buttons (interactive components)
- List
They work if, say, neither the modal or the page design frame are done as components. That’s not really a workable solution, though; I don’t want to have to sacrifice maintainability of my designs/artboards for maintainability of my components.
