listbox ipadx, ipady not working

[maxtimbo]

Perhaps not working properly is the better term here. If you:

import tkinter as tk
from tkinter import ttk

class MyApp(ttk.Frame):
    def __init__(self, parent, *args, **kwargs)
        ttk.Frame.__init__(self, parent, *args, **kwargs)
        self.parent = parent
        lb = tk.Listbox(self, width=30, height=20)
        lb.grid(row=0, column=0, padx=5, pady=5, ipadx=5, ipady=5)
if __name__ == "__main__":
    root = tk.Tk()
    MyApp(root)
    root.mainloop()

The Inner padding works, bout only on one side, that being the right side and the bottom. I have some things in the listbox and i just want to juke them off the edge of the box for readability. Any suggestions?
