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?


if (props.value != null) {
          value = props.value + '';
        } else {
          value = optionChildren;
        }
        selected = false;
        if (Array.isArray(selectValue)) {
          
          for (let j = 0; j < selectValue.length; j++) {
            if ('' + selectValue[j] === value) {
              selected = true;
              break;
            }
          }
        } else {
          selected = '' + selectValue === value;
        }
        props = Object.assign(
          {
            selected: undefined,
            children: undefined,
          },
          props,
          {
            selected: selected,
            children: optionChildren,
          },
        );
