Comment:

 After [https://wordpress.slack.com/archives/C02RQBWTW/p1624404225467900
 some discussion in Slack], the most recent pull request is the route we're
 going to take her.

 - Add the `regenerator-runtime` dependency.
 - Add it to the Webpack config.
 - Add it as a dependency of `wp-polyfill`.

 This should fix the issue plugins are experiencing. In a dev note, we'll
 call out that developers still needing `regenerator-runtime` should update
 their scripts to include this handle as a dependency and Core will remove
 this dependency from `wp-polyfill` in a future release.
