Option "Update Animation in Editor" is reset for child skeletal meshes

When the boolean is set on a child skeletal mesh, looks like it gets reset  

Specifically , at UActorComponent::ConsolidatedPostEditChange forces a reconstruction of the Blueprint, making the transient boolean to get reset to false on the child skeletal meshes

For some reason, for the main skeletal mesh component it does not lose the value

Open ML Deformer sample project. In Samples/MLDeformerSample.

Select BP_Emil BLueprint in the Outliner

Select SKM_LowerCostume

Set the option "Update Animation in Editor" (in advanced view)

Result : the boolean gets reset to false right after clicking on it (also the checkbox will look like you cannot check it).

This only happens on the child skeletal mesh components, not the root.
