Review Comment:
I agree that it's strange and I only used the original to keep the old
behavior after seeing the relevant test fail. I think the old buggy behavior
(before #1321) was to fail on matching attributes only, but match everything by
default.
CC @lordgamez, do you think it's OK to change this to the matching
attributes only?
