Looks good to me! Just a heads up, @hughhhh, in the last Superset meetup there was a request to add more context to PRs, specially why things are being changed, instead of just what. Would be nice to update the description to explain why you're making this change.

@betodealmeida updated the description! thanks beto

During our internal discussions related to #11478, someone mentioned we should probably not make ”Edit Datasource" so accessible because users can easily accidentally update other people's datasource and break their charts.
