[VP9-SVC] - Chrome user's webcam stopped on Firefox

Hello developers,
Currently I have an experience of VP9 support functionality on mediasoup v3 demo interface
I have a situation where the sharer’s camera (chrome) after a while (about 5-30s) is standing on the viewer’s side (firefox).

Step1: Visit the demo page and start the VP9 support meeting

Step2: User1: Join demo with Firefox browser & open camera
Step3: User2: Join demo with Chrome browser & open camera
Step4: Observe the webcam movement between Firefox and Chrome (after a while you will see the user’s webcam on the chrome side will be stuck on the Firefox side of the browser)

I don’t know what is the cause of this error, in core mediasoup or because the encode/decode between Firefox & Chrome is out of sync. I am using Firefox version 103.0.1 (64-bit) & Chrome version 104.0.5112.81 (64-bit)

Looking forward to receiving your feedback.
Thank you
