OnDrawGizmos() is never called when hideFlags is set HideInHierarchy when the object created.

OnDrawGizmos() is never called when hideFlags is set HideInHierarchy when the object created. And I changed the object's Hideflag to None. But still not called.

I tested some situation, and got some hints. I made an object that Hide flag is none, and the object called OnDrawGizmos() very well. And I change the object's option to HideInHierarchy and the object's still called OnDrawGizmos() very well.

I don't know what is right state, (Not called OnDrawGizmo(), or called the func in hide state.) but I think it was somethings wrong.

Anybody knows this problem? I need some solution.

For my bad English, I put some sample code in here.

 public class SomeComponents: MonoBehaviour
 {
     void OnDrawGizmos()
     {
          //some rendering code..
     }
 }

<< Situation 1>>

     void Create()
     {
         GameObject goObj = new GameObject();
         SomeComponents cpnt = goObj.AddComponent<SomeComponents>();
         goObj.hideFlags = HideFlags.HideInHierarchy;
     }
 
     void SomeFunc1()
     {
         goObj.hideFlags = HideFlags.None;
     }
 
     void SomeFunc2()
     {
         goObj.hideFlags = HideFlags.HideInHierarchy;
     }

In Situation 1, I create object and call SomeFunc1() => still NOT called OnDrawGizmos().

<< Situation 2>>

 void Create()
 {
     GameObject goObj = new GameObject();
     SomeComponents cpnt = goObj.AddComponent<SomeComponents>();
     goObj.hideFlags = HideFlags.None;
 }
 
 void SomeFunc1()
 {
     goObj.hideFlags = HideFlags.None;
 }
 
 void SomeFunc2()
 {
     goObj.hideFlags = HideFlags.HideInHierarchy;
 }

In Situation 2, I create object and call SomeFunc2() => still called OnDrawGizmos().!!

What is the problem?
