Errors are not reported in Chrome's console when SPPB's lazy loading is enabled. However, when disabled, there are repeated errors saying, "Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('<URL>') does not match the recipient window's origin ('<URL>')."

Please advise on the cause and how to correct it.
