title: jQuery masonry leaving gap
body: <p>I'm attempting to use jQuery Masonry in a project and it's not working properly: there's a gap in the top-right corner of the grid. I've tried adjusting the grid width and margins, which results in either one block per row or all blocks being run together (but still with a gap topright.)</p>
  
  <p>It doesn't actually look like the blocks are being rearranged at all, though Masonry is applying its class and assigning absolute positioning to the elements as expected.</p>
  
  <p>I was convinced that I was doing something wrong, but now I'm not so sure. I've taken a working fiddle from a similar question on Stack (http://stackoverflow.com/questions/11695574/jquery-masonry-almost-always-empty-spaces) and carefully modified it to use the dimensions I'm working with, and it just seems to be incapable of handling this selection of elements.</p>
