Further information
Reproduction steps, noticeable behavior, related issues, etc

If a plugin panics at any point after loading, then attempting to reload it will create an additional pane in the same state instead of reloading.

Reproduction:

• Run a plugin which is guaranteed to panic
• Load the plugin, then remove the panic and recompile
• Attempt to load the plugin again

#2929 will likely fix this, I will confirm next release since I got Zellij via Cargo rather than git main.
