Morph target for SK_BoxMorph_1 exceeds 1.0, causes the sphere shape to bend inward

In Content Examples, the morph targets assigned to SK_Box_Morph_1 exceed 1.0. While it's not "wrong" for morphs to go beyond that, it doesn't seem like it's a great demonstration in the asset. Going above 1.0 results in the sphere getting a little distorted.

1. Open Content Examples in editor.
2. Open the anim asset SK_Box_Morph_1_Anim.
3. In the Animation Editor, click Window > Anim Curves.

RESULT

As the animation plays, you can see the "B" curve (which is controlling the morphtarget) go above 1.0, which causes the vertices to bend inward.
