youtube video carousel weird positioning

Hello,

I created a carousel with 5 items, showing 3 of them and slides one at the time. all are youtube videos. everything works great, but when I click on the play button, it changes its position to the edge of the screen. is there a way that clicking play won’t change the item position?
I tested with infinite loop, autoplay, with both/none/only one of them but it stays the same.

Thanks
