title: ConstraintLayout: Realign baseline constraint in case if dependent view visibility was set to GONE
body: <p>Is there any way to realign baseline constraint for the TextView in case if dependent view visibility was set to GONE?</p>
  
  <p>My layout code:</p>
  
  <pre><code>&lt;android.support.constraint.ConstraintLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"&gt;
  
      &lt;TextView
          android:id="@+id/title"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="TEST TITLE"
          android:textColor="@color/black"
          android:textSize="24sp"
          app:layout_constraintLeft_toLeftOf="parent"
          app:layout_constraintRight_toRightOf="parent"/&gt;
  
      &lt;TextView
          android:id="@+id/subtitle1"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="SUBTITLE 1"
          android:textSize="11sp"
          app:layout_constraintBaseline_toBaselineOf="@+id/subtitle2"
          app:layout_constraintHorizontal_chainStyle="packed"
          app:layout_constraintLeft_toLeftOf="parent"
          app:layout_constraintRight_toLeftOf="@+id/subtitleSpace"
          app:layout_constraintRight_toRightOf="parent"/&gt;
  
      &lt;android.support.v4.widget.Space
          android:id="@+id/subtitleSpace"
          android:layout_width="12dp"
          android:layout_height="wrap_content"
          app:layout_constraintLeft_toRightOf="@+id/subtitle1"
          app:layout_constraintRight_toLeftOf="@+id/subtitle2"/&gt;
  
      &lt;TextView
          android:id="@+id/subtitle2"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_marginTop="4dp"
          android:text="SUBTITLE 2"
          android:textSize="14sp"
          app:layout_constraintLeft_toRightOf="@+id/subtitleSpace"
          app:layout_constraintRight_toRightOf="parent"
          app:layout_constraintTop_toBottomOf="@+id/title"/&gt;
  
  &lt;/android.support.constraint.ConstraintLayout&gt;
  </code></pre>
  
  <p>In this case, my layout looks like this:

  <p>When I'm setting <code>subtitle2</code> TextView visibility to <code>GONE</code> my layout will look like this:

  <p>So I'm wondering if there is some constraint which can realign baseline in the case if the dependent view is missing.</p>
