MySQL can normalize queries (like from digests) and adds spaces before and after the separating dot in qualified identifiers, e.g.
SELECT `db` . `table` . `column` FROM .... It can also allow partially quoted identifiers like "foo.bar or foo.bar". In both cases these are not parsed properly which results in query metadata not populating. Running these queries in the above formats executes without errors, so they appear to be considered as valid query formats by MySQL.
