Steps to reproduce:

1. Use Elasticsearch or Solr as a search engine.
2. Add Relation and Relation List field types to newly created Content Type. Additionally, on v4.5 add Taxonomy Entry Assignment field type.
3. Create single Content of newly created Content Type, fill every relation (including Taxonomy on v4.5).
4. Search for a document created for newly created Content in Elasticsearch or Solr and search for relation values, for example:

   "elastic_relation_list_value_ms": [
   "57"
   ],
   "elastic_relation_list_sort_value_s": "57",
   "single_relation_is_empty_b": false,
   "elastic_single_relation_value_s": "75"
   

5. Remove Contents that were related to newly created Content (and Taxonomy Entry in v4.5.
6. Empty trash.
7. Observe the document in Elasticsearch or Solr.

Result:
Related values are still present in the document.

Expected result:
Related values should be removed from the document.
