Comment (by peterwilsoncc):

 After further investigation, the underlying cause appears to be [52836]
 for #37189.

 In #37189 the `WP_Term_Query` class switched to caching individual term
 IDs in the main query cache, and them using those IDs to get each
 individual term object.

 On a site with unsplit terms, the `WP_Term_Query` cache no longer includes
 the tt_id relevant to the query.
