Multiple call to ref.current.rendition.next() not working

Hi,

I'm currently trying to animate swiping with epubjs-rn.
But to do that, I need to load three epub instance, to display prevPage, currentPage, and
nextPage.

To manage that, I need to call rendition.next() about three times.
But my problem is, sometimes it is not working.
Maybe because some contents of epub, some htmls are not yet loaded in the reader, and still not scrollable and visible.

Is there a way for me to somehow call a function to load more content on the epub?

Please help me, or if you have other way to do the animation. Please share with me. Thanks.
