Joining one participant to the room resulted in receiving two job requests when using JobType.JT_PUBLISHER

[xiaoxiper]

Hello, when I set the mode to JobType.JT_PUBLISHER, after 1 human user joined the room and two agents were started, I found that the agent service received 2 job requests. I'm using the cloud version of LiveKit. https://cloud.livekit.io/

The relevant logs are as follows:

The first time

The second time the job request was received, it appears to be for the same room, participant and tracks: participant {\n sid: \"PA_zsEsghxyD37t\"\n identity: \"identity_8f5d0634-aade-449b-a174-1dc1daff8514\"\n state: ACTIVE\n tracks {\n sid: \"TR_AMvDELgCWEaMSQ\", but with a different job ID: AJ_Viz3xTeNSgpP. This could indicate that the LiveKit server is sending duplicate job requests for the same participant joining the room.
