Object attribute support

[Masood Abdolian]

I need something like .dataset=${object} without data- prefix.

Input
<div .attr="${{foo: 1, 'foo-bar': 2}}"></div>

Output
<div foo="1" foo-bar="2"></div>

easy with custom elements ... you define a getter, and set an attribute per each object key/value pair ... otherwise, check uhtml-intents
