Mastodon's domain blocks & rationales ignore user approval when visibility set as "users"

Summary

Mastodon's domain blocks & rationales ignore user approval when visibility set as "users"

Original description

The description as published by the source.

Mastodon is a self-hosted, federated microblogging platform. In versions prior to 4.1.23, 4.2.16, and 4.3.4, when the visibility for domain blocks/reasons is set to "users" (localized English string: "To logged-in users"), users that are not yet approved can view the block reasons. Instance admins that do not want their domain blocks to be public are impacted. Versions 4.1.23, 4.2.16, and 4.3.4 fix the issue.
