As long as I tried, this doesn't happen on Konsole (Ubuntu), Windows Terminal, and PowerShell.
I'm personally interested in the difference between Terminal.app and others.
How about iTerm2?

[tompng]

It reproduced in macOS Terminal.app, iTerm2, Alacritty, Terminal inside VSCode, and also vterm in ci

I see. I could reproduce this issue. ( Terminal.app & Alacritty with tmux )
When fullwidth characters wrap just, display broken. It would be easier to understand if the width of the terminal emulator is shortened.
