Why zoomed in footage then go to picture-in-picture always exceed the boundary box?

I have run Jitsi SDK in Android, I tested some meetings and found some problems. When someone shares their screen and we zoom in the screen share then we go to picture-in-picture, the preview of PIP always exceeds the boundary box. It went normal when we are not zooming in on the screen share, is there a way to fix this? I tried to find a way to fix this but still have not yet found any solution. Below I attach the screenshot so we could understand the problem.
