The ResizingDragBar makes the editor resizable, so we need to set the CodeMirror height to 100%. This only happens when the Realtime Preview module is loaded. This fixes a critical issue introduced by I4deeda192b that caused blank renderings when scrolling large documents. Bug: T357794 Follow-Up: I4deeda192bdc233101ba61739a636f8fd143c1de Change-Id: Ib49d1d9e71df3653b13dfd44a8efedbf1ef9cd93
