As you can see in the screenshot the Fullscreen View of the editor seems messed up:
Additonaly, It seems like not possible to Set the Topic-Title from within the Fullscreen editor.
Huh didn’t even notice you could do that, the graphical bug should be fixed.
As for the title field, that’s strange but it seems to be the way discourse works.
No Problem at all I just prefer full screen editors if I it is a possibility thats why I noticed.
