Describe the bug

My React application creates a new window and then uses React createPortal to render into it. Whenever I try to render any shadcn component that pops up a dropdown menu (Select, Dropdown, Menu, etc.) and I activate the dropdown, it will appear in the main window instead of the new window.

Affected component/components

Dropdown, Select, Menu, any that has a dropdown

How to reproduce

1. Create a component that creates a window
2. Create an instance of Select or any other component that creates a dropdown
3. Render the Select into the window with createPortal

I've created an example project demonstrating the behavior in my Github.
