'verifymessage' fails for messages signed using segwit address

[3rror404]

Messages can be signed successfully with both legacy and segwit addresses using the signmessage command, but messages signed with segwit addresses can not be verified with the verifymessage command.

The messages seem to be signed correctly, as can be verified here: https://www.verifybitcoinmessage.com/

Examples

Legacy address

Address: p5iG9HLZoVCMNYCYyYHj4aPBJ6rwiHhg7n
Message: Hello, world!
Signature: H0drZIYwca61ZKCXJ0uEWNgwztgTwbX9Te70K18t8XVeFS8hcNO4fRxi7zpbgR9tbemYF0etnX3ybhqAJfUUTZ8=

Segwit address

Address: pkt1q6sj0mchq7ltwm8c9tpm2wteqmeldr2ye5lcr60
Message: Hello, world!
Signature: IH73zLeFgqeYZL0zSnS0bMbumiwYaiY7521KqrG4rjDKENMhPGJljlTAM86EPqeI4+CnXn7xoHXSMim/OsBPLUo=
