[BUG]: Unable to add class when adding Dom Component

[RJCAM]

GrapesJS Version used: 0.16.12 (current)

Just a strange behavior, I can add all the attributes I want when adding component directly inside canvas using dom components add function (like code below) but the editor always remove the class.

let component = editor.DomComponents.addComponent({
    tagName: 'div',
    content: 'Content text', // Text inside component
    style: {
        width: "100%",
        height: "100px",
        "background-color": "#ddd",
        color: 'red'
    },
    attributes: {
        title: 'divTitle', // This works
        id: "divID", // This works
        class: "someClass" // This is going to be removed
    }
});

The class is only added if we create the component first and then assign a class to it. Example, we add the code above and then we add the code below:

component.addAttributes({
    class: 'anotherClass'
});

Yeah, you have to use classes property, but I agree that is confusing (that because classes are treated a bit differently), so I'll try to make the initialization possible also with attributes.class value
