Hi,

I try to set data-* attribute to element with no luck on virtual-dom

For example:
This working:

hx`<a href="${pagination.links.next}">Next</a>`

But this is not:

hx`<a href="#" data-href="${pagination.links.next}">Next</a>`

I've googled and found this https://github.com/Matt-Esch/virtual-dom/blob/master/docs/vnode.md#custom-attributes-data-
which maybe related to my issue.
