Combining items: Paste Rich Text with Titles expected behavior

[cnewtonne]

I'm running into an oddity when attempting to combine items that causes the items to just disappear. It is reproducible and this is how ...

1) Create a new rich text info item
2) Create 2 RT children and populate each with some content.
3) Select both children / copy
4) Select parent item / paste special / paste rich text titles
5) Should notice the 2 children disappearing.
6) CTRL+z to recover the lost items.

To workaround it ...
Paste the children into a separate item (other than their parent).

Is this the expected behavior?
