Not showing InlineGraphic until I "realign text"

private function handler_insertInlineGraphic( event:RichTextEditorEvent ):void
        {
            var loader:Loader = new Loader();
            loader.contentLoaderInfo.addEventListener( Event.COMPLETE, handler_inlineGraphicLoaderComplete );
            loader.load( new URLRequest( event.value as String ) );
        }
       
        private function handler_inlineGraphicLoaderComplete( event:Event ):void
        {           
            var bmd:BitmapData = Bitmap( event.target.content ).bitmapData;
            var bm:Bitmap = new Bitmap( bmd );           
            EditManager( _textFlow.interactionManager).insertInlineGraphic( bm, bm.width, bm.height );
            _textFlow.interactionManager.setSelection( 0, 0 );   
            _textFlow.flowComposer.updateAllContainers();
            //_textFlow.interactionManager.setFocus();   
               
        }

This methos places the image and the space inside the TextFlow, but the space is blank until I do some kind of modification to the text, turn it bold, anything, then I can see the image.

any idea?
