2DAimOffset mesh skews across viewport when anim sequence is added to offest graph

When adding an animation sequence to a 2D Aim Offset, Owen's skeleton stretches and skews all over the viewport.

Appears to be similar in process to https://jira.ol.epicgames.net/browse/UE-5111, but results appear different than they did in 4.12.

1. Launch UE4Editor.exe ContentExamples.
2. Create a new 2D Aim Offset asset, targeting the Owen skeletal mesh.
3. Open the aim offset asset in Persona.
4. Drag AO_CC into the offset graph
