Disable Scrolling In Checkout Page

General General Questions

Hi,
If you fill out a form of a step, the page scrolls to the next step. I would like to disable (or adjust) the scrolling. But I can't find the trigger or the catch. What determines the scrolling? In which piece of code can I adjust this? Or what triggers the scrolling (id or hook?)?

js/tygh/checkout.js

replace

$.scrollToElm(elm);

with

//$.scrollToElm(elm);

Then clear cache
