After we uninstall comment module, the following code still lists comment_body field of comment entity.
\Drupal::service('entity_field.manager')->getFieldMapByFieldType('text_long');
Ideally, the comment entity fields should not appear as module is uninstalled.
After investigation, it was found that key_value table still has an entry of entity.definitions.bundle_field_map collection corresponding to the comment (name column). This leads to entity_field.manager listing the comment entity fields as well.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Tried to reproduce:
* Clean Umami install
* Enabled Comment module
* Checked key_value table, comment entry was there
* Uninstall comment module
* Checked key_value table, comment entry was gone
Can you reproduce this on a clean Drupal install?
Since there's been no follow up to #7 going to close out. if still a bug in D11 please re-open.
