This issue happened because of some miscommunication during the original patch review. Since we have the parent element in other outliner modes (Blender File, Data API) I was on the fence here. Rolling this back now so that when Show All View Layers is off we don't see the current View Layer top element. The fix is simple, but it was better to format the code around to follow the style in this file. Differential Revision: https://developer.blender.org/D11830
