title: Android Toolbar: small title text in landscape mode
body: <p>I'm testing the new Toolbar and AppCompat theme on Android and ran into a problem. My toolbar title text looks normal-sized on portrait mode but it became rather small on landscape mode although I didn't do anything in the code to change the title's text size. Here are the screen shots:</p>
