Test how mastodon-posts will work embedded:
This one does work (from my own server) what does not work is the embedded link (links to this site not the loerzweiler.online-site):
No 2 does not work fully (pictures don’t load)
No 3 does work (answer to one of my posts) no in the post
no 4 works, a random post from one of my lists.
No 5 does work
No 6 a random post with an embedded link to an article does not work fully
