HTML embed with a href nested in link component causes duplicate schema

This is super edge case and not sure if it merits a fix, but just adding here for documentation in case it comes up again.

A user added a link component, then nested an HTML embed with an a href in it. This caused the site schema to duplicate. That's the only known issue.

Feel free to close this as it's super edge case, not a big issue, and probably very difficult to fix.
