title: isScrollContainer doesn't work
body: <p>I have the next layout:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical"
      tools:context=".MainActivity"&gt;
  
      &lt;LinearLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="horizontal"
          &gt;
  
          &lt;Button
              android:id="@+id/button1"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="button1"
  
              /&gt;
  
          &lt;Button
              android:id="@+id/button2"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="button2"
              /&gt;
  
          &lt;Button
              android:id="@+id/button3"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="button3"
              /&gt;
  
      &lt;/LinearLayout&gt;
  
      &lt;EditText
          android:id="@+id/edittext"
          android:layout_width="match_parent"
          android:layout_height="0dp"
          android:layout_weight="1"
          android:gravity="top|left"
          android:isScrollContainer="true"/&gt;
  
      &lt;Button
          android:id="@+id/submit_button"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:text="Submit"/&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>I set android:isScrollContainer to "true" so that when the soft keyboard is shown, EditText will shrink and we can still see "Submit" button. <br/> <br/>
  But when I run the project on my device, the soft keyboard hides this button.<br/> <br/>
  Please tell me what is wrong.<br/><br/>
  <strong>Edit</strong> I've just tested it on my emulator and it works pretty fine and I'm sure it worked on my device as well. But something on the tablet must have been updated and have changed the behaviour.<br/><br/>
