On my computer (Windows 10, screen resolution 3000 x 2000, scaling of text and other elements set at 200% as the recommended value), the path browser is essentially unusable as the items overlap each other. See the attached image. 

I found that changing the following:

    def draw(self, x, y):
        # XXX This hard-codes too many geometry constants!
        dy = 40  # changed from 20

in solved the problem.

Another reason to replace IDLE's custom tree widget with hard-coded constants with ttk.Treeview.

I am closing this because I believe that #31552 will solve this problem.  For an initial check, run the following test code, extracted from
Click the [+] buttons.  I am curious whether commenting out the fix_scaling call makes any difference.

import tkinter as tk
from tkinter import ttk
from import fix_scaling

root = tk.Tk()
tree = ttk.Treeview(root)

tree.insert('', 'end', 'widgets', text='Widget Tour')
tree.insert('', 0, 'gallery', text='Applications')
id = tree.insert('', 'end', text='Tutorial')
tree.insert('widgets', 'end', text='Canvas')
tree.insert(id, 'end', text='Tree')

I ran the example you gave and it worked perfectly.
