Comment:

 I recommend testing this ticket along side #55352.

 With this change in place, it means that the early call to `get_term_by`
 populates the cache for the taxonomy query. This means one less query per
 page on tag pages.

 Even without this benefit, limiting the query, makes the query return
 first, as SQL, stop processing once the limit is meet.
