// is a logical child of the ContentControl3D, not the ContentPresenters that host the content.
// In order to inform the Content/BackContent elements of which side they reside on, we must
// attach the IsOnFrontSide property value to them via a value converter that is set on the
// TemplateBinding of the ContentPresenters' Content property. If we do not do this, then the
// IsOnFrontSide property value does not get inherited by the elements shown in the control.
// This is important when BringIntoView is called on an element in the ContentControl3D and we
// need to figure out on which side of the control it exists. This workaround is only for
// the Content and BackContent, but not the elements created by the ContentTemplate or
// BackContentTemplate properties.
