The underlying code change (throttling same-process, cross-origin display:none iframes) that this enterprise policy overrides has been enabled in stable releases since early 2023. Since known issues have been dealt with, we intend to remove this enterprise policy by early April 2024 (M124). https://chromeenterprise.google/intl/en_ca/policies/#ThrottleNonVisibleCrossOriginIframesAllowed The discussions around the throttling issue (and it's resolution) can be found at https://bugs.chromium.org/p/chromium/issues/detail?id=958475.
