The RTCPeerConnectionIceErrorEvent constructor should have an optional init dict

Or, alternatively, at least one of the init dict members should be required.

My guess is that we want to require at least errorCode to have a meaningful event.

Event constructors are mostly pointless and not used, so unless there's some invariant to be maintained that would simplify implementations, I would make it as simple as possible, giving everything a default value. That way you don't even need any prose to say what the defaults are, and implementations can just copy-paste the IDL.
