Link attribute removed

I am trying to verify my subscribe page on my Mastodon account, which requires to include a link back to Mastodon like <a href="https://instance.domain/@username" rel="me">Mastodon</a>. I added the link to my subscribe page, but when I inspect it, the rel="me" attribute isn’t there.

Anyone knows how to fix this?

I have added the following to my description on my write.as-page:
@username

On the Mastodon-profile I have added a link to the write.as-blog:
Blog | https://my.blog

This is working fine so far. Good luck
