Okay,

I did a few tests. The Problem also appears if I enable the visual (tab) editor via functions.php, like described here: BBPress Codex, and even if I use this Plugin: bbPress Enable TinyMCE Visual Tab

This is what it looks like on the Website: directupload.net Image

And this is how it looks like in chrome dev tools: directupload.net Image

Can’t believe that I am the only one with this problem… Or am I doing somethings wrong?
