This change refactors how attributes like `popovertarget`, `interesttarget`, and `commandfor` are displayed. Instead of using `ref` directives for async lookups, it now uses `Lit.Directives.until` to asynchronously fetch and render a link to the related element. The resolved related element is cached to improve performance and is used when editing the attribute value.
