hubzilla's mention markup is so different from Mastodon's that it almost looks purposefully engineered to have nothing in common with it lmao

Mastodon: <span class="h-card"><a href="account_url" class="u-url mention">@<span>username</span></a></span>
Hubzilla: @<a class="zrl" href="account_uri" target="_blank" rel="nofollow noopener">display name</a>
