The will-navigate event that apps use to prevent navigations to unexpected destinations as per our security recommendations can be bypassed when a sub-frame performs a top-frame navigation across sites.
Patches
11.0.0-beta.110.0.19.3.08.5.1
Workarounds
Sandbox all your iframes using the sandbox attribute. This will prevent them creating top-frame navigations and is good practice anyway.
