bug (InvalidCharacterError) on fieldError themeConfg property when multiple classes added to the class attribute

[angelokeirsebilck]

Describe the bug

Using the themeConfig and setting the fieldError property with multiples classes breakes the property.

  fieldError: {
                            attributes: {
                                class: 'text-error text-xs mt-1'
                            }
                        },

The token added to the DOMTokenlist is in the wrong format and my formie error message is printed twice. When i use only one class e.g. 'text-error' it does work.

Steps to reproduce

1. Render form with the themeConfig
2. use the fieldError property
3. set the class attribute to something with two classes ( 'text-red-500 font-medium text-sm')
