  I noticed that the example demo below loads after 10 items. Should the docs be corrected or the demo?

the infinite scroll component should load the first 20 items in the list then show the next 20 every time the bottom of the list is reached.

today it is:

Vue.set(state.pageInfo, 'currentPage', parseInt(headers['X-Page'], 10));
Vue.set(state.pageInfo, 'nextPage', parseInt(headers['X-Next-Page'], 10));
Vue.set(state.pageInfo, 'totalPages', parseInt(headers['X-Total-Pages'], 10));
Vue.set(state.pageInfo, 'totalResults', parseInt(headers['X-Total'], 10));
