Message:

Taxonomy: Don't discard keys when merging queried terms from different taxonomies.

For values of fields like id=>parent, the keys of the array must be
maintained as part of the query results.

Introduced as part of #40496. See [38667], [40513].

Props miyauchi, dany2217, pcarvalho.
Fixes #41293.
