BUG: appendTo not working with trait manager

HTML
        <div id="gjs">
        
        <div class="traits-container"></div>
          <div style="padding: 25px">Hello World!!!</div>
        
        </div>
        
        <h1>
        Append trait manager 
        </h1>
        
        <div class="traits-container"></div>
        

Js

      const editor = grapesjs.init({
	      container: '#gjs',
        fromElement: true,
        height: '100%',
        storageManager: false,
        traitManager: {
                appendTo: document.querySelector('#traits-container'),
          },
        plugins: ['gjs-blocks-basic'],
        dragMode: 'absolute'
      });

Why trait manager is not appended to the custom container?
