When catching the fetch error with .catch() it still shows the error in the console.

Steps to reproduce:

1. Go to basic example https://www.bryntum.com/examples/gantt/basic/
2. Open the code editor
3. Then paste the whole code

import { Gantt, StringHelper } from '../../build/gantt.module.js?459924';
import shared from '../_shared/shared.module.js?459924';

const gantt = new Gantt({
    appendTo          : 'container',
    dependencyIdField : 'sequenceNumber',

    project : {
        autoLoad  : true,
        transport : {
            load : {
                url : 'https://something.com'
            }
        }
    },

    columns : [
        { type : 'name', width : 250 }
    ],

    // Custom task content, display task name on child tasks
    taskRenderer({ taskRecord }) {
        if (taskRecord.isLeaf && !taskRecord.isMilestone) {
            return StringHelper.encodeHtml(taskRecord.name);
        }
    }
});

gantt.project.load().catch(err => console.log(err));

4. Check the console.
