Repro steps:
- Make two cubes - one a child of the other with some offset.
- Select the parent cube.
- Press F for frame selection.
- Double-press F for frame selection with tracking.
- Notice how double-F frames the pivot rather than the bounds so the framing is not the same as for single-F.
- Test the above with center/pivot toggle set to both center and pivot. Behaviour between single-F and double-F should be consistent in both modes.
