I've transformed Peter's test into TAP test that runs ~20 seconds and reliably reproduces problem on my laptop.
And I observe that commenting out condition in following code fixes the test.
            //if (!(statusFlags & PROC_IN_SAFE_IC))
                h->data_oldest_nonremovable =
                    TransactionIdOlder(h->data_oldest_nonremovable, xmin);
