[issue10734] test_ttk failure under Windows

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

It looks like the Windows buildbots have been failing since the tk upgrade (at least, I'm assuming it is related since there haven't been any tk changes recently).

======================================================================
FAIL: test_heading_callback (tkinter.test.test_ttk.test_widgets.TreeviewTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\tkinter\test\test_ttk\test_widgets.py", line 945, in test_heading_callback
    self.fail("The command associated to the treeview heading wasn't "
AssertionError: The command associated to the treeview heading wasn't invoked.
