Right.  That's not a bug.

Many people imagine that an invalid DKIM signature says something bad
about a message.  They are mistaken, no matter how often they repeat
that misconception.  There is nothing in DKIM that says anyone should
remove signatures from incoming mail for any reason.  If a signature
doesn't validate, the correct thing to do is to ignore it.
