Summary

As observed in #611 when trying to upgrade to Lit@2, that this following export * syntax was not being supported, which can be found in lit's index.js

import"@lit/reactive-element";import"lit-html";export*from"lit-element/lit-element.js";

Details

Should break that change out into a standalone PR since it will take some time for community sourced dependencies a little time to catch up and don't want that to block anyone else from adopting Lit@2 or any other dependencies that use that syntax.
