[Bug]: `DOMElementValue` cannot read HTML text or comment

[stloyd]

What happened?

When reading HTMLElement details, we get everything that's inside of it, but if it contains a mix of text and elements, we cannot easily get only the text.

How to reproduce?

<div>
    <span>foo</span>
    bar
</div>

We're unable to get a bar value alone.

Data required to reproduce bug locally

As above.
