Frames

Ordering

Frames should be ordered where frame children come first, followed by the frame element itself:

[
  other_element,
  frame1_child1,
  frame1_child2,
  frame1,
  other_element,
  frame2_child1,
  frame2_child2,
  frame2,
  other_element,
  ...
]

If not ordered correctly, the editor will still function, but the elements may not be rendered and clipped correctly. Further, the renderer relies on this ordering for performance optimizations.
