When the cache flush bit is set on host address records in a response, known records are cleared and replaced with the contents of the packet. However even if the response contains the same records as before, this caused it to be marked as modified, and response modified callbacks are sent for every incoming packet. Instead, ensure that the response is only marked as modified if a previously unknown address record is added, or if a previously known address record is removed. The issue wasn't found by the existing testDecodeWithNoChange test, because it used a service record for testhost2 instead of testhost1, so the address records were ignored.
