Shoulder "Popping" on the UE5 Mannequin

In certain positions, the shoulders of the UE5 mannequin can look like they are dislocated.

This is a result of the post process animation blueprint and the extra bones designed to maintain volume around the character joints. Comparison with the Post Process Animation blueprint enabled and disabled

The same system seems to work fine on Metahuman characters, but on the mannequin it causes this issue around the shoulder in more extreme poses - likely made worse by the way they have applied the bone weights around the shoulders of the Mannequin. For other characters based on the UE5 Mannequin skeleton this probably won't be an issue, but can be fixed by disabling the Post Process blueprint.
