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?


break;
    }
    processChild(element, Component);
  }
  
  function processChild(element, Component) {
    let publicContext = processContext(Component, context);
    let queue = [];
    let replace = false;
    let updater = {
      isMounted: function(publicInstance) {
        return false;
      },
      enqueueForceUpdate: function(publicInstance) {
        if (queue === null) {
          warnNoop(publicInstance, 'forceUpdate');
          return null;
        }
      },
      enqueueReplaceState: function(publicInstance, completeState) {
        replace = true;
        queue = [completeState];
      },
      enqueueSetState: function(publicInstance, currentPartialState) {
        if (queue === null) {
          warnNoop(publicInstance, 'setState');
          return null;
        }
        queue.push(currentPartialState);
      },
