Different lib-jitsi local video track behavior than meet.jit.si

I’m using lib-jitsi-meet to integrate Jitsi in my ReactJs app. But the self image in local track created is flipped (180 degrees on Y axis) as compared to the mirror image in meet.jit.si (or hangouts etc). What do I have to change to make lib-jitsi create a mirror imaged local track?
p.s. I’m using my own deployment of jitsi meet, if that matters.

What does jitsi-meet do about it is flipping the video with css. There is even a right click menu on the local video that can flip it.

Thanks Damian. rotate-y : 180 degree on the video tag works.
