%%Comments%% look alright over here (Obsidian v.1.5.3, Sandbox vault):
How does it behave in the Sandbox vault or a new vault? How about in your vault using the default theme, restricted mode with a restart, and no css snippets enabled? Other troubleshooting steps to try.
Also, does it happen in all notes or just that 2023-W50 one?
Just a guess, but it could be a bad theme and/or css snippet interaction.
