Comment (by azaozz):

 WebKit excludes the width of the vertical scrollbar when calculating when
 to apply the CSS "@media screen and (max-width: 900px). The calculated
 width matches $(window).width(). Firefox and IE > 8 include the scrollbar
 width, so after the jQuery normalization $(window).width() is 884px but
 window.innerWidth is 900px. 23817.patch is based on that.

 Also using window.innerWidth excludes IE < 9 that don't support @media.
