Created an issue to track this:
JDK-8229983 <https://bugs.openjdk.java.net/browse/JDK-8229983> flatMap
still prevents short circuiting when using .iterator()

Oops thanks.
So I think the issue is that StreamSpliterators.java has this line
bufferSink = ph.wrapSink(b::accept);
that creates a Sink that never returns true in cancellationRequested()
which is needed to get flatMap() to stop looping.

Not really sure where to send this.
flatMap was fixed so that it doesn't prevent short circuiting.

If you replace the test cases in the ticket with versions that use
.iterator().next() instead of .findFirst().get() then the problem
still happens.
I just tested this with openjdk:14 on docker hub.
