Adding css with html element forbid repeating group scroll

Hello there !
I got an issue, where I am trying to get my elements to adjust their height to the screen size. For that I used the html element with a style tag, that set the height with vh. However, my repeating group that is a vertical scrolling layout, doesn’t allow scrolling anymore. I am stuck at the top of my repeating group with only a few element, and the scroll is off ! Do someone know why ?
