Importing a native P2WPKH script & pubkey via `importmulti` fails:

Since the pubkey is required due to issue #14405, I tried to import a native P2WPKH script together with its pubkey. It looks like importmulti assumes legacy P2PKH?
But maybe I'm doing something wrong.

Input...
* address `bcrt1qlqx4gx4qftlfe94n48ttchsptxqwt7je7tddna`
* pubkey `027dbe32bdf80ef2312f8280bd37bf69c31322745af5ebded6294969ff19c20da3`
* scriptPubKey: `0014f80d541aa04afe9c96b3a9d6bc5e015980e5fa59`

Call: `importmulti '[{"scriptPubKey": "0014f80d541aa04afe9c96b3a9d6bc5e015980e5fa59", "pubkeys": ["027dbe32bdf80ef2312f8280bd37bf69c31322745af5ebded6294969ff19c20da3"], "timestamp": "now", "watchonly": true}]' '{"rescan": false}'`
