Comment(by duck_):

 The same problem is also encountered when trying to set an item as the
 child of another item but has the same ID (i.e. the same menu-item-object-
 id). An example of this is with Hello World post (id = 1) and
 Uncategorized (id = 1).

 Side note: issues also crop up with clashing IDs when you try to make a
 third item (say the About page) a child of the clashing item further down
 the menu:

 Start with:
 {{{
 - About
 - Hello World
 - Uncategorized
 }}}

 Move About to child of Uncategorized:
 {{{
 - Hello World
 - Uncategorized
 ---- About
 }}}

 Save, and you end up with:
 {{{
 - Hello World
 ---- About
 - Uncategorized
 }}}
