[Bug]: v7 Default Export Causes Component to Fail

[dyeoman2]

What version of React Router are you using?

7.0.0-pre.6

Steps to Reproduce

1. Set up a React application using React Router 7 (^7.0.0-pre.6).
2. Create a component that uses the ShadCN Dialog component or AliceCarouselModule from "react-alice-carousel".
3. Export this component as a default export.
4. Use this default-exported component in a React Router 7 route.

Expected Behavior

The component containing the ShadCN Dialog or AliceCarouselModule should render correctly regardless of whether it is exported as a default or named export.

Actual Behavior

The component containing the ShadCN Dialog or AliceCarouselModule renders correctly when it is exported as a named export but fails to render when exported as a default export.

When adding a log inside of the component that is exported as a default export, the data comes across as undefined but comes through correctly when exported as a named export.

This behavior did not occur prior to migrating from Remix to React Router 7.
