Seleceted subcategories in admin panels not appear in "tree" view

[maorb]

I think this is a bug I've long time ago.
On the admin panel, suppose I define some categories and sub-categories, then when editing a post I see these categories with checkboxes to chhose category/ies for a post.

When checking only a sub category, the view is changes and this selected category appears on the top of the categories list, and not viewed as a subcategory. Its functionality behaves ok, and the slug shows the hierarchy (if %category% is being used), but by looking in the visual tree of categories in the edit posts now, the admin can not know the what is the category's hierarchy.

When checking the boxes of the category and also its parent(s), so the tree is being preserved in its view, but this is not a solution, since then the %ctegory% slug holds only the parent as the slug.

I think that the desired situation is that assigning post to a sub catgegory will remain the visual tree of category hierarchy as it is.

Attached jpeg to example this. On the left, the category "subcat1-B-1" is in its place and the hierarchy of categories of parent-child-grandchild is ok. After selecting the grand child for the category of the post and updating, this category goes to top and its hierarchy view is gone, and can't know what the hierarchy is. With a lof of categories and category's children, that may very very confusing...

Thanks
