Using super() on tk.TopLevel, but do not generate second window?

Question

I am attempting to implement a trivial MVC application. When super().__init__() is called, two windows are generated in my python application.

What is the appropriate usage when attempting to inherit from tk.TopLevel, when I only want to generate one window?

import tkinter as tk
from tkinter import ttk

class View(tk.Toplevel):
    def __init__(self, controller):
        super().__init__()
        self.controller = controller
        
    def exec_main(self):
        self.mainloop()
        
class Controller:
    def __init__(self):
        self.view = View(self)

if __name__ == '__main__':
    app = Controller()
    app.view.exec_main()

Doing something like super().__init__(master=self) or super().__init__(self) does not seem to be the solution.

An alternative approach would be to do something like this for the main:

import tkinter as tk


class View(tk.Toplevel):
    def __init__(self, master):
        tk.Toplevel.__init__(self, master)

class Controller:
    def __init__(self, root):
        self.view = View(root)

if __name__ == '__main__':
    root = tk.Tk()
    root.withdraw()
    app = Controller(root)
    root.mainloop()

But this seems wasteful.
