On some pages, the DOM is limited to what is in the current viewport

Note that this affects both the Full Page screenshot and Article mode

It looks like some pages (like imgur) are doing some smart-loading of the page based on the viewport. As a result, we are sending up incomplete views as only part of the page is being loaded into the DOM at any given point in time.

The workaround for this is to zoom out of the page (ctrl--) until you can see the whole page, ensuring that the entire DOM is loaded, and then clip it at that point, but ideally we can do something in code to force the entire DOM to load.
