I’m always unsure if these kind of topics is better in ux or bug sorry if this topic is misplaced.
I often use my firefox window on responsive and I came across this minor css issue when I want to send a private message : the title form is partly hidden
And if I reduce the window even more, I can’t really see what title I wrote. Well, you got the idea
Little infos just in case :
Browser : Firefox 64 bits
OS : Windows 10 Pro
Until recently, the title form was on a line below, and it worked well on full screen ou windowed.
