Wrong HTTP status for HEAD request

A GET request for a word that doesn't exist in a managed resource (stopwords or synonyms) returns "404 Not Found", but the HEAD request for the same child resource returns "200 OK" as if the word actually exists.

$ curl -i "http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar" | head -n 1
HTTP/1.1 404 Not Found

$ curl -I "http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar" | head -n 1
HTTP/1.1 200 OK

Solr 8.6.3 returns "404 Not Found" for both GET and HEAD requests for a non-existing child resource. This is how it SHOULD be according to RFC 2616:

The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request.
