Describe the Bug

When using the experimental.svg flag in Astro 5.6.2, passing an imported .svg file to the <StarlightPage frontmatter={{ hero: { image: {} } }} /> component results in an schema validation error.

Expected Result

No validation error

Actual Result

Invalid frontmatter props passed to the <StarlightPage/> component.

hero.image: Did not match union.
Expected type { file: object } | { dark: object; light: object } | { html: string }
Received {}

Note: the /core and /from-markdown routes do not throw an error, the error seems to be limited to the frontmatter prop.
