Only shown if VisualEditorEnableDiffPage is set, or query string param 'visualdiff' is present. Currently: * All VE javascript is loaded (could be cut down to just DM code) * The entire Parsoid HTML of both revisions being compared is loaded * Both Parsoid HTML docs are parsed into VE DM trees and diffed Bug: T167508 Change-Id: I151fc9bab3d3032f50c8d11be6b54e45a06fcc34
