This is INTENDED to meet both the TV2.5 and TV2.6.
For TV 2.5, there is no remote-control service, only send-tab. Send-tab is based on presentation api, while remote-control is based on JPAKE over TLS. In Fennec side, it doesn't know what kind of services the discovered devices have. Thus, when Fennec discoveries presentable devices, it will know the device provides send-tab service. The fennec won't know the discovered devices provide remote-control services or not until receiving their broadcast for remote-control information via mDNS.

I believe this situation happens only when Fennec discoveries a presentable device but Fennec doesn't receive any information indicating that device provides remote-control service.

The root cause is that we have two protocol for two services. If we only have one protocol to do the services, then we can avoid that.

After discussion with Tori(UX), this behavior is not abnormal.
