livekit-agents==1.2.11

We are using the livekit session with:

...
turn_detection = MultilingualModel(),
vad=silero.VAD.load(),
...

as well as Deepgram as STT

Problem

We've noticed an issue that we at times receive a transcript from the STT model.
In traces we can see that we have a eou_detection span, however we don't have a user_speaking span and we also don't receive any user_state_changed event.
If the EOU model detects the speech as final the agent will continue in the conversation.

However, this is very problematic for us when the previous state of the user was away, because then our agent will continue to think that our the user is away and after some time end the call.

I have seen PR #3559 -- however this does not appear to change the user state.
