The lightbox isn't closed when you click on some areas

Hello

Minor problem I found when testing on my website. If you click on a pic on an article, it's displayed on a lightbox. Very cool thing that I love since I started to use Easyblog. But I found a quick problem on EB5 that wasn't on EB3.9.

If you look at my attachment, you'll see a pic on a lightbox, 2 red areas, and 2 green areas. Green areas means that if you click here, the lightbox will be closed. Red areas means that if you click here, the lightbox will be NOT closed. On EB3.9, all those areas would be green, so, I don't know if it's an intended behavior, or if it's a bug.

Thanks for reading
