How to skip the div keep rowVirtualizer.totalSize

[hoahiep506]

Hi, I am try to fix some bug because some one missed a div element when he setup.
In Examples we have

<div ref={parentRef}>
       <div style={{ height: `${rowVirtualizer.totalSize}px` }}>
              {rowVirtualizer.virtualItems.map(virtualRow => ( ... ))}
       </div>
</div>

and here in my project

<div ref={parentRef}>
        {rowVirtualizer.virtualItems.map(virtualRow => ( ... ))}
</div>

This make some bugs and scroll bar lagging so much.

=> There is a way to keep this code and make it work ?
I know this is a stupid question but maybe I get luck :), because this project is too big and this code applied too many times, fixing it by follow Examples will take so much time.

Thanks you.
