On start error, the REPL window closes immediately so one can't read the error

[teto]

I am using f603de5

I dont have a lua interpreter in PATH so running IronRepl lua logically fails BUT it does so in a weird way, e.g., iron.nvim starts a window which immediately disappears so I can't read what's on it. Then when I try to quit, neovim complains because of running jobs:

:lua vim.pretty_print(vim.api.nvim_list_chans())

So I wish a failing REPL would not disappear (hoping it's not a behavior due to some of my other plugins) and I dont think it used to be the case, something must have changed recently.

This could be interesting to support :checkhealth iron.nvim too to see if all REPLs are correctly configured.
