title: Xamarin Forms Label/StackLayout Rotation Issue
body: <p>I'm trying to rotate some labels in xamarin forms but there are some problems. If i rotate a single label the text will trim and there will be only some letters visible, i putted every label inside a stacklayout and i rotated the stacklayout itself with -90 degree as the code below</p>
  
  <pre><code>&lt;StackLayout Spacing="0"
               Rotation="-90"
               VerticalOptions="Start"
               HorizontalOptions="End"&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
          &lt;Label Text="ABCDE" TextColor="Black"/&gt;
      &lt;/StackLayout&gt;
  </code></pre>
  
  <p>the labels are rotated correctly, no text is trimmed. the problem is now that the <code>VerticalOptions</code> or <code>HorizontaOptions</code> of the stacklayout are not working properly. When i set the <code>VerticalOption</code> to "Start" it will show everything not in the top but somehow 25% from the top. The <code>HorizontalOptions</code> has another issue when i set it to "Start" or "End" like the image below:</p>
