addType in domcomponent for html conditionals generates a <div> in visualization

Find the answer myself, for anyone that may have the same problem : extend the render part and set a display:none to the object to be rendered, this will not affect the html.

			var textnodeType = domc.getType('textnode');
			domc.addType('comment', {
			      model: textnodeType.model.extend({
			        toHTML() {
			          return `<!--${this.get('content')}-->`;
			        },
			      },{
			        isComponent(el) {
			          if (el.nodeType == 8) {
			            return {
			              tagName: 'NULL', // just need this to avoid some parser rule
			              type: 'comment',
			              content: el.textContent
			            }
			          }
			        },
			      }),
			      view: textnodeType.view.extend({
			    	  render: function () {
			    		  this.el.style.display = "none";
				          return this;
			    	  }
			      }),
			    });
