Shows Safari incorrectly autofilling multiple autofill scopes

When there are multiple autofill scopes in the same form owner, Safari ignores the autofill scope and fills all fields across all scopes. Firefox and Chromium do not.

Spec:
https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill-processing-model:autofill-scope

Example (codesandbox app):
https://jxkyfc.csb.app

Source code for example:
https://codesandbox.io/s/autofilling-shipping-billing-addresses-forked-jxkyfc?file=/src/index.html

The attached video shows this incorrect behavior in Safari.

In contrast, if there are multiple form owners, then Safari respects the autofill scope and only autofills one scope at a time:
