Helper to identify the entire aggregation area that should be skipped when searchin for focusable elements.
If the currently focused element is part of the aggregation being removed or destroyed,
the entire aggregation area needs to be skipped sinceh its DOM element will be removed
leaving no focusable element within the aggregation.

@param {sap.ui.core.ManagedObject[]} aChildren The children that belong to the aggregation
@returns {HTMLElement|null} Returns the DOM which needs to be skipped, or 'null' if no relevant area is found.
