Feature Policies are currently not replicated when frames are swapped out to another process (OOPIF)
Until crbug.com/661271 is resolved, this can be supported by replicating the Feature-Policy HTTP header value(s) to the remote frames.
In the remote process, the parent frames will be remote, but should have valid FeaturePolicy objects, which can be used when calculating the (local) child frame's policy.
Once crbug.com/662171 is addressed, this will also need to account for any iframe attributes in the parent frame. These will need to be replicated in the remote child frame as well as its own policy headers.
