Nit: "is failing" => "fails"

Nit: something like "IceTransportPolicy does not match existing policy" would be better.

> Source/WebCore/Modules/mediastream/RTCPeerConnection.cpp:310
> +        return Exception { InvalidModificationError, "IceTransportPolicy do not match" };

Nit: something like "IceTransportPolicy pool size does not match existing pool size" would be better.
