Mentions of users with . in their usernames aren't rendered correctly

[FitikWasTaken]

💡 Summary

Any mentions of users with . in their usernames are getting cut after the dot. According to the webfinger specs these 4 symbols are allowed: _ - . ~ ( https://www.w3.org/community/reports/socialcg/CG-FINAL-apwf-20240608/#names )

CherryPick supports the first two, and I have never seen a Fediverse software that supports creating an account with a tilde

However, there are examples of accounts with a dot using different software:

Bridgy Fed: @[email protected]
Threads: @[email protected]
PeerTube: @[email protected]

🥰 Expected Behavior

It should be rendered as a normal mention.

It was fixed in Sharkey, there's a related Sharkey commit: https://activitypub.software/TransFem-org/sfm-js/-/commit/3b5bfe6f6a1701e9abfcd4e7f97a4ff348d6ffbe

🤬 Actual Behavior

It's getting cut and username that should look like @[email protected] is rendered as @cool@[email protected] and it's definitely incorrect
