title: Position Tkinter complex grid
body: <p>I am making some test with Tkinter and I tried to make more complexity but it doesn't work :</p>
  <pre><code>from tkinter import *
  
  root = Tk()
  
  frame1 = Frame(root, bg='blue',width=200,height=200)
  frame1.grid(column=0,row=0, sticky=&quot;news&quot;)
  frame1.grid_propagate(0)
  
  frame4 = Frame(frame1, bg='yellow',width=100,height=100)
  frame4.grid(column=0,row=0,sticky=&quot;news&quot;)
  frame4.grid_propagate(0)
  
  frame5 = Frame(frame4, bg='orange',width=20,height=20)
  frame5.grid(column=0,row=0,sticky=&quot;news&quot;)
  
  frame6 = Frame(frame4, bg='pink',width=20,height=20)
  frame6.grid(column=0,row=1,sticky=&quot;news&quot;)
  
  frame7 = Frame(frame4, bg='red',width=20,height=20)
  frame7.grid(column=0,row=4,sticky=&quot;news&quot;)
  
  root.mainloop()
  </code></pre>
  <p>Why the frame7 is not in the row 4 but in the row 3 ?</p>
