Bug report

Bug description:

When mixing tk.Checkbutton and ttk.Checkbutton (and maybe custom class Checkbutton)
tkinter behaves weirdly (calling method of one object changes the other too).
It is because ofname collision.

importtkinterastkfromtkinterimportttkwn=tk.Tk()tk.Checkbutton(wn)ttk.Checkbutton(wn)print(tk.Checkbutton(wn).winfo_name())print(ttk.Checkbutton(wn).winfo_name())

this example prints

!checkbutton2!checkbutton2

This happens because oftk.Checkbutton._setup overriden method
which is not called in ttk.Checkbutton.
I think that that method can beerased, whichwould solve the problem,
but I'm not sure why it is there in the first place.

CPython versions tested on:

3.12
