I asked WhiteNoise, since he was marked as moderator and the last one who replied, but he probably overlooked my message. Are there other options to request re-opening a thread?
Yes, you’re right. The original bug report actually showed a negative margin. I thought it was the same problem, but actually it seems to be a different one, since I can’t reproduce such a negative margin, although I tried using the same “office building” emoji and different fonts and resolutions. The only issue I see is that there is no or a very small margin, contrary to Windows.
That also hints to a generally different behavior of Chrome on Windows and MacOs, not something that could easily be fixed in Obsidian.
