The
Cross-Origin-Opener-Policy, when set on a customer's page which opens a Trinsic popup, can block necessarypostMessagecommunication between the popup and the customer's page.The
same-origin-allow-popupsvalue is meant to resolve this, but on Safari specifically, it breaks if the popup is first opened toabout:blankand later redirected to our domain (as we were doing).Safari dictates that the popup must be launched to our actual domain in order for
window.openerto remain intact, so this change does that.
