Issue Resolved / Feature Added

ImageItem rendering time is higher when scrolling in VirtualList.

Resolution

The main root cause is one rendering so many React Elements again. So I tried to cache the React Elements and re-rendered only children prop or some props with a CacheReactElementContext.

Additional Considerations
