Current behavior 😯

I discovered this while trying to override component for a styled ListSubheader in our app. I tried it for ListItem as well but not others - it seems that when wrapping a component with styled, the component prop is lost and TS errors out.

Expected behavior 🤔

component prop is not lost

Steps to reproduce 🕹

Research direction

Start with the linked CodeSandbox reproduction and inspect how styled wraps ListSubheader and ListItem, focusing on the TypeScript props. Confirm that the component prop remains available on the styled components without errors, then verify the behavior across the reproduced cases.
