hook_ENTITY_TYPE_translation_delete not called

To reproduce:

1. Write a hook_ENTITY_TYPE_delete implementation and put a \Drupal::logger(__FUNCTION__)->notice(__FUNCTION__) inside of it
2. Write a hook_ENTITY_TYPE_translation_delete implementation and put a \Drupal::logger(__FUNCTION__)->notice(__FUNCTION__) inside of it
3. Create a node in the site default language
4. Translate the node into another language
5. Delete the node in the default language

Expected result:

1. You see the notice that the node will be deleted in all the languages
2. You get a log message that shows hook_ENTITY_TYPE_delete was called
3. You get a log message that shows hook_ENTITY_TYPE_translation_delete was called

Actual result:

1. You see the notice that the node will be deleted in all the languages
2. You get a log message that shows hook_ENTITY_TYPE_delete was called
3. You DO NOT get a log message that shows hook_ENTITY_TYPE_translation_delete was called

Note: If you directly delete a given translation you DO get a log message that shows that hook_ENTITY_TYPE_translation_delete was called.
