HideFlags.HideAndDontSave does behaviour in 2017.4.0f1

Questions & Answers
1

HideFlags.HideAndDontSave is not destroying any object created in edit mode when change scenes or switching to play mode.

If I use any HideFlags.DontSave, the gameObject will still be there but not will not shown in Hierarchy.

Any ideas how to fix this? This is the intented behaviour?
