Description
Bug report form
- I have done a basic search of the issue tracker to find any existing issues that are similar.
- I have checked that my version is at least the latest stable release available via my installation method.
Describe the bug
When we open a buffer editor using ctrl+o, and then suspend the editor. Result: nushell also gets suspended.
How to reproduce
I don't know how to reproduce with other editors, but for vim/nvim there is the steps:
> $env.config.buffer_editor = 'vim' # set editor to vim
> blabla # type something
# run ctrl+o to open buffer editor
# run ctrl+z to suspend the editor
Expected behavior
I expect nu to not get suspended with the buffer editor as well. Only the editor should be suspended.

Research direction
Start by tracing the buffer-editor path triggered by ctrl+o and the suspend behavior when vim or nvim receives ctrl+z. Reproduce the issue on Linux with the configuration shown, then inspect how the editor and reedline handle suspension; done means suspending the external editor no longer suspends Nushell as well.
