webrtcbin: no offer is being sent
Our usual flow as follows:
- on-negotiation-needed is invoked
- application invokes "create-offer"
- application invokes "set-local-description" with offer
- application sends offer to the other party via signalling server
However, the local description is sometimes (randomly) already set and therefore on-negotiation-needed is not invoked and flow is not executed. How can local-description be already set when checking if negotiation is needed? The webrtcbin is sendonly.
