The curse of being a frontend programmer is that when you spot an issue on a website you frequent, you have to fix it, no matter how much time it takes ... At least I now have a dark-themed post composer and it says "Post" instead of "Toot" xD

Actually, that last one required me to enable the CSS :has() flag in Firefox and had me encountering a bug with it as well, but whatever, hovering over the button fixes that again :p
