On occasion, a RemoteLayerTreeDrawingArea may be outlived by one or more of its RemoteLayerTreeDisplayRefreshMonitors. Upon destruction of the RemoteLayerTreeDisplayRefreshMonitor, this may cause the monitor to access a method of its drawing area, which has been deallocated. This results in a crash.
