fix: mouse wheel and touch scroll not working over popover

[pa4080]

This PR gracefully resolves #607, also resolves #542. These issues are caused by an issue with Radix-ui/primitives which still open for over a year and a half - it is described here: [Dialog][Popover] Scrolling issue when Popover inside Dialog #1159

The current solution simulates an arrow down/up key press when we use the mouse wheel over the problematic popover primitive component.

Hi, coming back here to add suggestion
In our application with this impl we still had problems with scroll, but this time at touch devices

So our final fix is

const useFixScrollForModaledPopovers = () => {
   const touchStartRef = useRef<number | null>(null)

  const onScroll = (event: WheelEvent<HTMLDivElement>) => {
    event.stopPropagation();
    const isScrollingDown = event.deltaY > 0;

    if (isScrollingDown) {
      event.currentTarget.dispatchEvent(
        new KeyboardEvent('keydown', { key: 'ArrowDown' })
      );
    } else {
      event.currentTarget.dispatchEvent(
        new KeyboardEvent('keydown', { key: 'ArrowUp' })
      );
    }
  }
  
  const onTouchStart = (event : TouchEvent<HTMLDivElement>) => {
     touchPosRef.current = event.changedTouches[0]?.clientY ?? null
  } 
  
  const onTouchMove = (event: TouchEvent<HTMLDivElement>) => {
     const touchPos = e.changedTouches[0]?.clientY ?? null;
     if(touchPosRef.current === null || touchPos === null) return;
     
     e.stopPropagation();

     const isScrollingDown = touchPosRef.current < touchPos;

     if (isScrollingDown) {
       e.currentTarget.dispatchEvent(
         new KeyboardEvent('keydown', { key: 'ArrowDown' })
       );
     } else {
       e.currentTarget.dispatchEvent(
         new KeyboardEvent('keydown', { key: 'ArrowUp' })
       );
     }

     touchPosRef.current = touchPos;
  }
  
  return { onWheel, onTouchStart, onTouchMove }
}
