adding label_class param to FloatingField construction adds a label-class attribute to the textarea dom instead of adding class to the label

[htao00]

As title says:
FloatingField('my_floating_field', label_class='ms-3')

results in:
<textarea name="my_floating_field" cols="40" rows="10" label-class="ms-3" class="textarea form-control" placeholder="my_floating_field" required="" id="id_my_floating_field"></textarea>

The expected behavior should be same as adding the wrapper_class parameter, where it correctly adds the classes to the <div id="div_id_my_floating_field"> dom
