I debugged the new code locally a bit but I am not sure that we get the expected result here. If I don't miss anything $event->getData() returns new \ArrayIterator(3 => null]); here.

The null part can be ignored as we don't have a fully built form here, but is 3 really the index we expect here?

Good catch, I was not aware arrays behave like this; index should have been 0 not 3.
I updated the code and test accordingly.

The
CollectionTypehandles not only arrays but alsoArrayAccess&Traversable. However when setting itskeep_as_listoption,array_valueswould then be called and crash.To avoid this, this PR reindexes the data by getting its keys and unsetting them. This is because unsetting in a loop can produce counter-intuitive results; e.g.
ArrayIteratorwould skip indexes.Note that #57430 mentions another issue that would be fixed by #59910.
