Issue - tag tree disintegrates when you try to make it a child of another tag.

[JohnnyArtist]

Version - 1.0.0-rc9

For example:

1. • I take this tag tree - Anatomy Human -> Legs, Hands, Torso, Head
2. • And put it into Anatomy tag.
3. • After this tag tree of Anatomy Human disintegrates and ends up looking like this - Anatomy -> Anatomy Human, Legs, Hands, Torso, Head
4. • But it must be like this - Anatomy -> Anatomy Human -> Legs, Hands, Torso, Head
