As described in https://www.chromestatus.com/feature/5148698084376576 , JavaScript modal dialogs, triggered by $6, $6, and $6, will be blocked in Google Chrome if triggered from a subframe whose origin is different from the main frame origin.
This policy allows overriding that change.
If the policy is set to enabled or unset, JavaScript dialogs triggered from a different origin subframe will be blocked.
If the policy is set to disabled, JavaScript dialogs triggered from a different origin subframe will not be blocked.
This policy will be removed in Google Chrome version 95.
