Indeed, basically that's the same issue as reported in bug #44063:
the constructor misses to properly initialize the OuterIterator.

Might be the case indeed. I wanted to add a comment over there, but I am not allowed to. So here:
> How could you say this is not a bug? Please reconsider!
> There is one invariant which says: »the pointer in all new iterators points at the first
> element of the collection that has to be iterated.«
>
> Hence a new iterator a that wraps another new iterator b points to the first element of b.
I am very happy with and grateful for the SPL contribution to php. I really hope the behaviour from
all iterators from the iterator zoo will be consistent. I think these bugs are certainly no bogus.
It's a contract violation and that's painful to me.

That looks like #44063

Note that one get get the expected behaviour from the implementation in
ext\spl\internal\cachingiterator.inc after correcting the following bugs in that file:
add private $flags as class member
on line 50 change flags into $flags
on line 50 delete CIT_ prefix
