title: A Unity prefab instance attached to the scene is receiving unwanted scaling
body: <p>I'm managing a dynamic UI based on canvas. The UI is created with Layout groups (vertical and horizontal).</p>
  <p>One of the dynamic components of this UI is a prefab that I'm instantiating, filling with the needed information, and attaching to the parent that will dynamically place it through a vertical layout.</p>
  <p>I can't understand why this instance is attached and rescaled to &quot;0.683&quot;. To make it work correctly I have to scale it back to 1 from code. This behaviour since pretty strange... I'm wondering if you have suggestions to avoid the need to resize the object from code. Even if it is not such a problem I rather keep this flow clean.</p>
  <p><strong>Note:</strong> If I attach the same object manually from the editor, the behaviour is correct and the item is keeping a scale of 1.</p>
