Why do gameObjects keep automically expanding themselves in the Hierarchy?

Unity 5.0.1
Has anyone else experienced the issue of the gameObjects being expanded in the hierarchay for no apparent reason?
Every time i do a search in hierarchy bar, and then return to the normal view, some gamebojects have been expanded from being collapsed. This is becoming frustrating.
Is there a way do avoid this?

initially "Bed" is collapsed.


now I do a search for something.


then I clear the search bar

the game object has automatically expanded 200 items.
It is becoming a hassle to keep having to re-collapse everything when I have thousands of items.

 

This is something I still find annoying to present day. All sorts of actions expand the gameObjects, which seems to defeat the purpose of sorting them out into hierarchy. Still no fix for this?

 

Any fix on this?
