hobgoblin: .html() output for <hr/> differs for shallow() vs. render()

Testing a minor component that renders only `

`. I was attempting to evaluate testing with outputs from shallow() vs. render() when I found differences in the results from .html().

The shallow renderer's `shallowWrapper.html()` returns `

`

The static renderer's `renderWrapper.html()` returns `

`

Is static rendering with cheerio causing the strange "how do we represent self-closing elements" differences?

Is there a mention in the docs that nothing is guaranteed about outputs from `.html()` and `.text()`?

Is there a stated/doced bias for which renderer to prefer?

Should I tell my [consistency hobgoblin](https://en.wikiquote.org/wiki/Consistency) to go join the troll under the nearest bridge?
