Issue

I'm getting a very odd rendering bug when writing a git commit message body using Neovim. On the first line (sometimes others, too) spaces are being replaced with the characters from the first line in the comment below the message. The anomalies temporarily go away if I delete a line, but come back as soon as I continue typing. The commit message saves fine, without those characters, but as you can tell typing commit messages is really hard for me. I think this is Electron-related because the same thing happens in VS Code's integrated terminal. macOS's built-in terminal and iTerm work fine.

I wasn't sure whether to report this here or Electron, or Neovim repo 🤷

Start by reproducing the rendering problem in vanilla Hyper on macOS while editing a Git commit message with Neovim, then compare it with the built-in terminal and iTerm. Check whether the same behavior occurs in Electron-based terminals such as VS Code; done means spaces render correctly while typing and the saved commit message remains unaffected.
