Component properties in Actor Details Panel

Sometimes the properties of a Component show up when the owning Actor is selected in the World Outliner. I'm trying to understand when this happen, and how to make it happen.

C++ Actor with UPROPERTY Component as root component.

This shows the UStaticMeshComponent properties in the Actor's Details Panel.

Header:

#pragma once

#include "GameFramework/Actor.h"

class UStaticMeshComponent;

UCLASS()
class AMyActor : public AActor
{
public:
    GENERATED_BODY()

    AMyActor();

    UPROPERTY(VisibleAnywhere)
    UStaticMeshComponent* Mesh;
}

Implementation:

#include "MyActor.h"

AMyActor::AMyActor()
{
    Mesh = CreateDefaultSubobject(TEXT("MyMesh"));
    SetRootComponent(Mesh);
}
