On a second thought, assertWaitForSelectedText("world") seems better. I'll
replace it in the next patch.

+                new OverviewModeBehaviorWatcher(getActivity().getLayoutManager(), true, false);

+        assertNotNull("Could not find 'tab_switcher_button'", button);
+        singleClickView(button);
+        overviewModeWatcher.waitForBehavior();
+
+        // Switch back to the tab view from the tab-switcher mode.
