2. Issues with the Zellij UI / behavior / crash

Issue description

I've configured a keybind for "run" to execute a command. When creating a new pane immediately after the run, zellij exits. I'm able to attach to it afterwards.

Minimal reproduction

❯ zellij --version
zellij 0.43.1

Add the below keybind under the tmux section in config.kdl

        bind "g" {
            Run "top" {
                close_on_exit true
                floating false
                x "15%"
                y "15%"
                width "70%"
                height "70%"
            }
        }

As soon as it opens, create a new pane immediately with alt-n. Zellij should have exited.
