There’s a small bug with short display names in the new account dropdown at the top of the page.
I can’t seem to upload screenshots here but the part above the red line at the top is shorter (less wide) than the part below it, when opened, and the display name is short enough.
Not really a bug, but it does look a bit weird with small usernames or first names. I will see what can be done about it while not having a bunch of extra space when not hovered.
