title: React pagination component number of item displayed issue
body: <p>I simply don't know why I have 10 Items displayed instead of 8?
  I'd like A hint as I'm not formidable on react.</p>
  <p>On my demo I have 10 movies displaying on the page they should be 8. Not sure why the page PAGE_SIZE = 8 doesn't do the job.</p>
  <p>Any help is much appreciated.</p>
  <p>Thanks in advance
