Scrub Timing Problem on mobile

Hi Folks
i have a small timing issue:

PW= werksgast

here you see on the bottom a terminal with some cards flyling over the terminal. works fine so far. but on mobile the timing dont work correct. when i open the page the first time the cards are already gong when i come to this area. when i reload the page it works. i assume some lazy load propblems. how can i wait to trigger the animation until the user is in that area and everthing is loaded?
