[webrtc-pc] RTCCertificate Interface should (or should not) be backed up.

steely-glint has just created a new issue for https://github.com/w3c/webrtc-pc:

== RTCCertificate Interface should (or should not) be backed up. ==
in "4.10.2 RTCCertificate Interface"
we say 
"The RTCCertificate object can be stored and retrieved from persistent storage by an application. " 
It isn't clear if this should be backed when the rest of a browser is backed up or indeed sync'd (i.e. bookmarks etc).

In contrast to the rest of localStorage, there is no mechanism for a service to access the privateKeys - so no way for them to be backed up and restored (e.g. in case of a phone being immersed in water).

What is the intended behaviour?
