Failed to execute 'createOffer' on 'RTCPeerConnection': Illegal invocation

Tried taking a useragent from 0.13.8 to 0.14.0 today and noticed an odd failure on useragent.invite().

I'm able to get as far as the sessionDescriptionHandler-created event I'm listening for, then things seem to fall down.

Submitted too early - was going to mention I was hoping I hit some weird race condition, so I stopped passing things through via useragent.invite(myURI, options) and instead pass them "earlier" via the UA sessionDescriptionHandlerFactoryOptions - no luck there.

Rolled back to 0.13.8:
