Oh that's wonderful! I tried to test out bold within italics and italics within bold and both worked... this time. Thank you for your efforts, they are super appreciated!
More generally, I love being proven wrong about PieFed. On Lemmy if you say "this feature does not exist", then five years later it's still an accurate statement, whereas on PieFed... it's so hard to keep up with because it's so readily changed, by such dedicated fans like... well, YOU! 😊🎉💪🤩
