Is this a new update?

Is this indeed part of a recent update?
I hope it’s not my Obsidian having a glitch and then reverting back to what it was…
EDIT: According to another user on Discord, this seems to actually been fixed for macOS. The user said that it has been fixed for a while now, but maybe I didn’t even bother trying to add ? so to me it was still there up until today. Glad that it was fixed!
