Possible Bug: Control + Left bracket (ctrl + [) clears prompt in zsh

[exothe]

I'm using zsh with vi mode. To enter vi mode, I usually press ctrl+[ as this is more comfortable as hitting esc. Pressing esc works properly, I get into vi normal mode of zsh, but pressing ctrl+[ clears my prompt and then gets me into normal mode.

It seems like ctrl+[ is not always clearing the entire prompt, but just everything that has been typed since the last change from normal mode to insert mode. That's why ctrl+[ only clears the "test" in the last prompt of my example gif, because I've hit esc before.

My ghostty version: Ghostty 1.0.1-dev+0000000

Config: Initially I thought it would be a config issue, but ctrl+[ is not listed as a keybind. I've tried to disable the keybind using keybind = ctrl+left_bracket=unbind, but this has no effect. Using keybind = ctrl+left_bracket=ignore completely ignores the keybind, so it doesn't clear the prompt, but also doesn't get me into normal mode.

So I have no keybinds in my config. The entire config looks just like this:

background-opacity = 0.8
window-decoration = false

I've noticed this as well, I can reproduce the same 'delete the most recent insert' behavior. I'm using Ghostty 1.0.1 on macos 14.7.1 w/ zsh 5.9. I haven't got a clue about how to start debugging something like this but would be happy to help do so if anyone has ideas!

actually just took the time to look through other discussions and there is a fix which at least allows me to use ctrl-[ to exit insert mode in this thread: #5071
