Full height rows broken in IE 11

Our new site’s background doesn’t show up in most versions of IE11 when the full height row option is enabled. We tested this in a couple different versions of IE with varying results. On IE v11.31193 (Win7) the rendering works just fine. On IE v11.0.9600.18450 (Win8) as well as on online browser testing tools, the background does not show up.

In investigating on an affected computer, I observed an error being thrown in the ultimate_bg.js file when calculating the offset of the containing DIV. Calculating the offset() of a non-displayed element may return undefined, and in stepping through the breakpoints watching the error be thrown, it does seem probably that the element is not displayed at the time of calculation, returning an undefined result as a part of chained non-nullsafe method calls, which blows up. I was unable to determine what the current version of the VC Ultimate Addons is, but request that you either update the Ultimate Addons version or open a ticket with them.
