Done.

         // Test the IME window is hidden from the content view when the content
         // view loses its focus

Tests that the IME window does not get hidden when the content view loses its
focus.

[yabinh, 2016/10/18 08:57:49]

Done.

         final ContentViewCore contentViewCore = getContentViewCore();
         final View view = contentViewCore.getContainerView();
         assertTrue(view.requestFocus());
 
         final TestInputMethodManagerWrapper immw = new TestInputMethodManagerWrapper(getActivity());
         contentViewCore.getImeAdapterForTest().setInputMethodManagerWrapperForTest(immw);
 
         immw.showSoftInput(view, 0, null);
         assertFalse(immw.isHidden());
 
         final EditText urlBox = (EditText) getActivity().findViewById(R.id.url);
 
         assertTrue(urlBox.requestFocus());
 
         // Now another view has taken focus. The original view loses its focus
         // and the input method window should be hidden

[Changwan Ryu, 2016/09/09 01:07:29]

When another view (URL box) takes focus, we do not hide the IME window.

Done.
