[Bug]: MultiSelect dropdown scroll listener not removed when component destroyed while open

What happened?

When a MultiSelect / MultiSelectDropdown / MultiSelectQueryInput dropdown is open and its parent component gets destroyed (e.g. closing an edit modal via the X button without first clicking elsewhere to blur the input), the document-level scroll event listener added by setListener() is never removed. beforeDestroy() only removes the menu DOM element but never calls removeListener().

What did you expect to happen?

The scroll listener should be cleaned up whenever the component is destroyed, regardless of whether the dropdown was open or closed at that moment.

Steps to reproduce the issue

1. Open any book's edit modal → Details tab.
2. Click the Genres input to open its dropdown (this calls setListener())
3. Immediately close the edit modal via the X button, without clicking elsewhere first
4. beforeDestroy() fires while showMenu is still true, and removeListener() is never called — confirmed via console logging that document.removeEventListener('scroll', ...) is not invoked for this instance
