The environment_indicator entity forms don't have form titles, so when you view the form in the Seven theme, you just see the shortcut star button.
Add form titles to the add/edit entity form pages, like other entity forms in Drupal core.
Redefine the environment_indicator.default form handler as separate add/edit handlers, so we can detect the operation in the form builder method, and use a different title for each.
Set the title of the edit form dynamically, with the entity label.
The admin pages to add/edit an environment get proper titles.
The environment_indicator config entity type gets separate form handler names, but they still use the same EntityForm class.
None.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
It's better to use _title_callback in the route definition. See node.routing.yml for an example.
I've updated this to add dynamic title handling for the edit and delete form pages, and put it in a merge request with a tugboat preview.
