Same problem here, as mentioned earlier: "It seems that calling
ArrayIterator::offsetUnset moves the internal pointer to
the next element when removing the first index"
Is there any progress on a fix?

It seems that calling ArrayIterator::offsetUnset moves the internal pointer to
the next element when removing the first index:
$a = range( 0,3 );
$b = new ArrayIterator( $a );
for ($b->rewind(); $b->valid(); ) {
echo "{$b->key()} => {$b->current()}\n";
$b->offsetUnset($b->key());
}
var_dump($b->getArrayCopy());

Please ignore my comment above. The offsetUnset() method unsets elements using
their index. Changing the code to this gives the expected result (0, 4):
$items = new ArrayObject(array(0, 1, 2, 3, 4));
foreach($items->getArrayCopy() as $item) {
if(in_array($item, array(1, 2, 3))) {
$items->offsetUnset($item);
}
}
var_dump($items->getArrayCopy());

I have the same problem, used this code:
$items = new ArrayObject(array(1, 2, 3, 4, 5));
foreach($items as $item) {
if(in_array($item, array(2, 3, 4))) {
$items->offsetUnset($item);
}
}
var_dump($items->getArrayCopy());
Expected result: array(1, 5), actual result: array(1, 3, 5).

Sorry, I should clarify that the code above gives:
array(1) { [1]=> int(1) }
Whereas you'd probably expect:
array(0) { }
