Using Masonry within a grid item causes extra space on resize

[mseymour]

I've noticed that when I use Masonry within a grid item, when I resize my page (even when reducing all scripts and styles down to just csswizardry-grids and masonry) which would cause my items to reflow, I get a large amount of space on the right and/or bottom of my page, causing scrollbars to appear. This happens in the latest Chrome dev build, latest Safari, iOS 7 Safari, and iOS Chrome. All that I can figure out is that if I set a background color on html along with my page's background image, when it reflows, the extra space is colored the html background color. Otherwise, the body's background is used.

I've also opened an issue at Masonry's github page regarding this.
