When you apply position : fixed; and then return you will reset the position of your body because a fixed element isn't part of the page's flow

We must then change it's height from 100% to 100vh so the element's (in this case the body) height takes the whole screen and prevent any scrollbar to appear since we defined a height.

.overflowHidden {
  overflow: hidden;
  margin: 0;
  touch-action: none;
  -ms-touch-action: none;
  /* position: fixed; we get rid of this line which resets the flow of the page */
  /* height: 100%; we change 100% to 100vh */ 
  height: 100vh;
}
