💡 Summary

Lately Bluesky has begun one-way federation into ActivityPub. However, unlike Misskey, Bluesky allows dots (.) in their user IDs. Since MFMjs don't expect dots in the username part of the user, mentioning those users will end up broken result.

🥰 Expected Behavior

The whole User ID (e.g. @[email protected]) will be parsed as user.

🤬 Actual Behavior

ID before dots (@example in the case above) will be parsed as user and the rest will remain as string.

📝 Steps to Reproduce

1. Open any of the Misskey server (or MFM-supported site- no matters) and open note post.
2. Type any mentions including dots in their username part.
3. Open preview. (If you want you can just post it)
