Camera led indicator not turning of when muting in embedded mode

### Steps to reproduce

1. Start a call inside element web using element call.
3. In the lobby activate the video and jump into the call
4. Inside the call mute and unmute the camere -> (the led indicator does not update)

5. Disable the video browser permissions so that all streams are stopped.
6. new permission prompts will appear to rerequest the permissions -> accept those
7. mute unmute the video stream -> now it works

This indicates that the IFrame EC is properly starting/stopping the tracks. But EW is not stopping the track form the preview.

### Outcome

#### What did you expect?
The camera led indicator should represent the mute state
#### What happened instead?
The camera led indicator will not turn on/off
