Subobjects can change sorting order in Blueprint Subobject Editor

Subobject sorting is not stable in the Subobject editor, so the UX is bad if you are creating complex hierarchies because it's difficult to keep track of newly added or reordered components.

• Create Blueprint and add 3 Scene Components to the root component in the Blueprint editor
• Note the hierarchy will be DefaultSceneRoot->Scene2, Scene1, Scene
• Add a 4th Scene Component to the root and note the hierarchy resorts to DefaultSceneRoot->Scene, Scene1, Scene2, Scene3
• This can cumbersome if you are working with complex hierarchies
