The SimpleDialog keyboard tests generate key events after focus_force(),
which on Windows are dropped until the toplevel is mapped, so they could
fail intermittently (seen on the Windows10 buildbot as
test_return_no_default). Wait until the window is mapped in these tests,
as GH-152599 did for the other keyboard tests.

Writing new tests
=================
Precaution
----------
New tests should always use only one Tk window at once, like all the
current tests do. This means that you have to destroy the current window
before creating another one, and clean up after the test. The motivation
behind this is that some tests may depend on having its window focused
while it is running to work properly, and it may be hard to force focus
on your window across platforms (right now only test_traversal at
test_ttk.test_widgets.NotebookTest depends on this).
