I happened to notice that React will throw `Hooks can only be called inside the body of a function component` if a sibling element calls `ReactDOMServer.renderToStaticMarkup`. I have a [fiddle](https://jsfiddle.net/er4kL3of/) that shows this behavior (I think you need to manually open your console to see the error).

If you wrap the sibling element in a component or even just assign it a variable, this issue does not occur.

It's easy to get around and is a pretty specific bug, but why might this be happening?
