AFAICS that's correct behavior.  I think you're confused about SQL
syntax: the way you've written it, the "ia.id = 21" condition is
part of the left join's ON clause, and therefore it cannot cause any
rows from the left side of the join to be omitted.  (Hint: those
parentheses are just noise.)  Perhaps you meant to write WHERE ia.id = 21?
