Importing public key from keys.openpgp.org fails with "no user ID"

Running (up to date) 18.04 LTS I'm trying to import a public key from the somewhat new but OpenPGP key spamming resistant key server at keys.openpgp.org:

$ curl -s 'https://keys.openpgp.org/vks/v1/by-fingerprint/723E343AC00331F03473E6837BE5A11FA37E8721' | gpg --import
gpg: key 0x7BE5A11FA37E8721: no user ID
gpg: Total number processed: 1
$

This key fails to import (GPG does not report that any keys were imported).

$ gpg --version | head -n2
gpg (GnuPG) 2.2.4
libgcrypt 1.8.1
$

This makes it impossible to use most of the keys stored on the keys.openpgp.org keyserver and forces users (who want / need to use key servers) to instead work with SKS keyservers which do not prevent signature spamming, on a GPG build which lacks fixes against signature spamming. Which puts Ubuntu 18.04 LTS users at great risk of becoming victims of signature spamming, breaking their GPG installations in ways which are difficult to debug.

This issue has been previously discussed and solved in Debian at https://bugs.debian.org/930665
