An initial post on micro.blog when parsed for mf2 has a u-in-reply-to on itself. The u-in-reply-to should only appear on the reply posts, not the initial post.

My assumption is this is because typically this page is used for replies in the conversation view and the same logic is used for both. When creating this h-entry you might just want to check and verify the u-in-reply-to doesn't equal the u-url. If they are the same, then don't display the u-in-reply-to.
