title: Android password visibility toggle not working with support library 25?
body: <p>I have implemented a TextInputLayout with a password field in the usual way:</p>
  
  <pre><code>&lt;android.support.design.widget.TextInputLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"&gt;
  
      &lt;EditText
          android:id="@+id/returning_password"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:hint="@string/prompt_password"
          android:inputType="textPassword"
          android:maxLines="1"
          android:textSize="14sp" /&gt;
  
  &lt;/android.support.design.widget.TextInputLayout&gt;
  </code></pre>
  
  <p>This worked fine when using the Android support library up to version 24.0.2, but after switching to 25.0.1:</p>
  
  <pre><code>compile 'com.android.support:design:25.0.1'
  compile 'com.android.support:support-v4:25.0.1'
  compile 'com.android.support:appcompat-v7:25.0.1'
  compile 'com.android.support:support-vector-drawable:25.0.1'
  </code></pre>
  
  <p>I no longer see the password visibility toggle (a.k.a. "eye icon") in the widget. Changing to the latest version 25.1.0 does not fix this problem.</p>
  
  <p>Is there anything that I missed and need to change in combination with the support library 25, or could this be an Android issue?</p>
