Why does setAttrs update text in a span but not a div?

I'm trying to dynamically change header names of skills on a custom sheet. If the attribute is in a span, it updates when I change the value of the attribute. However if it is in a header or div it does not. Is this a roll20 thing or is that normal javascript behavior. setAttrs({strength_name: "Dexterity"}); will change the text in <span class="attribute-name" name="attr_strength_name">Strength</span> but not in <div class="attribute-name" name="attr_strength_name">Strength</div>

Divs cannot hold attribute values on roll20. Only inputs, spans, selects, and textareas can. (Off the top of my head - if there are others, divs are not among them.) attribute values and names like this are a pure roll20 behaviour, and are only enabled for the above elements.

Thanks, Roll20 has some weird behaviors.
