Get Parent - Get the display element that contains a given element
This action traverses up the object hierarchy to find the closest containing display element (the direct parent if it is a display element,
and otherwise the lowest parent in the hierarchy that is a display element).
Trigger [not required]
<Element> (non-repetitive trigger): The element whose parent is needed.
<Parent> (non-repetitive exit): The parent of the given element (or, if the <Element>
trigger is missing, the display element that contains the action itself).
Note: If the closest containing display element is a view (or another top level display element), or there is
no parent that is a display element, no value is returned.
