The native autofill popup could be positioned by a cross-origin iframe outside that iframe's bounds, over the embedding page's UI, enabling clickjacking or spoofing of trusted UI.

Apps are only affected if they embed untrusted content in iframes within windows that also display trusted UI. Apps that do not embed untrusted third-party content are not affected.

Do not embed untrusted content in iframes inside windows that display trusted UI.
