Does the print window contain the word "Print" on all versions of Windows?

Your guess is as good as mine.  I think I have a few VMs that still work I can
try it on.  Alternatively, I could land it with a little extra logging and see
how it goes through the main builders.

+  EXPECT_CALL(win_observer_mock, OnWindowOpen(_))
+      .WillOnce(DoCloseWindow());
+
+  // When the print dialog closes, close the browser.
+  EXPECT_CALL(win_observer_mock, OnWindowClose(_))
+      .WillOnce(CloseBrowserMock(&ie_mock_));
+
+  // Launch IE and navigate to the window_print.html page, which will
+  // window.print() immediately after loading.
+  LaunchIEAndNavigate(window_print_url);

 // Test fixture for tests related to the context menu UI. Since the context
