Pills with just an icon should be circular
The translation dialog pill is not circular, which is odd because it works fine with other pills that have just one icon:
@exalm said it's probably related to the horizontal and vertical margins being different and that the translation dialog uses an icon at 32px while others use it at 24px.
I could prepare a 24px version of the flag icon to fix the specific issue on the translation dialog, but if the CSS needs fixing anyway maybe that's the better solution?
