🐛 Fix check for display name to check if type is string before

Prevents potential errors by ensuring that `el.type` is not undefined before accessing its properties, specifically when checking for a click handler in the accordion component.

Adds a check to confirm that `el.type` is not a string and exists before attempting to access `el.type.displayName`. This prevents unexpected behavior when `el.type` is not an object with a `displayName` property.
