Can't use row style class on groups

Apparently there is a bug that doesn’t allow the fieldset tag to work with the row class. Is it possible to define a different tag to use instead of the fieldset tag? Here is the schema that i’m using:

schema: {
    groups: [{
        styleClasses: "row",

        fields: [
            {
                type: "input",
                inputType: "text",
                label: "First Name",
                model: "firstName",
                placeholder: "First Name",
                required: true,
                styleClasses: "col-xs-12 col-md-6",
            },
            {
                type: "input",
                inputType: "text",
                label: "Last Name",
                model: "lastName",
                placeholder: "Last Name",
                required: true,
                styleClasses: "col-xs-12 col-md-6",
            },
            {
                type: "input",
                inputType: "email",
                label: "Email",
                model: "email",
                placeholder: "Email Address",
                styleClasses: "col-xs-12 col-md-6",
            }
        ],
    }]
}

Basically, I want two columns for the form (unless the screen is too small). But because of the fieldset issue with the row class, I get the full width row and 50% width columns, but they are stacked vertically. So the column widths are correct, but instead of the 2 columns being side-by-side, they are half-width columns, one on top of the other, with lots of empty space to the right.

Is there anyway to set an option to substitute a different tag for the the fieldset tag? Or some other way to accomplish what I’m looking for?

The fieldset can be changed by passing a “tag” into VFG.

<vue-form-generator tag="div" ... />

This will change all of the “fieldset” tags into “div”, for example.
