Scroll synchronization of List and Grid lagging #746

Hi, first of all thanks for implementing a great and easy-to-use library. I cant get rid of one issue though - when I try to sync the scrolling of grid and list calling listRef.scrollTo() inside Grid's onScroll() function, the list lags behind.

You can see this unwanted behaviour in following example when you try dragging horizontal scrollbar: https://codesandbox.io/s/react-window-scrollto-issue-jxq838?file=/src/App.tsx

Hi, I used 'react-custom-scrollbars-2' for syncing the scroll of two list and it works very well.

hi, do you have a demo about this situation? I use react-custom-scrollbars-2 wrap my VariableSizeList, and the onScroll of react-custom-scrollbars-2 won't call at all
