On certain cases with SSR'd pages (i.e. Next.js), if we have some hydration issues, the Flickity component may first (or intermediately) render null, while still calling
componentDidMountandcomponentDidUpdate.Without a valid node, the app crashes trying to instantiate Flickity on null:
This patch fixes that, by ensuring that
this.carouselexists before trying to instantiate Flickity with it, ensuring thatthis.flktyexists before trying to access it.
