Currently it's not possible nor makes sense to select items at different
levels. That's what you are trying to do selecting at the same time part
of the contents of a delimiter object and one of the delimiters. However
originally when the cursor gots out an inset the whole inset was selected.
I don't remember when this behaviour was changed.
