Really? What editor does this? Vim/Neovim definitely will undo the change with a single 'u' press, and every GUI editor I've ever used will undo the change immediately with a single ctrl+z.

Ah, thanks for the correction. I'm wrong on how common this is.

I just tested CLion, VS Code, and Sublime Text. I thought all three behaved as described, but only CLion did. I wish it was more common though, I find it a lot more intuitive and clear on what's happening.
