ReactDOMTextComponent = function (props) {
  // This constructor and its argument is currently used by mocks.

Text nodes violate a couple assumptions that React makes about components:

 - When mounting text into the DOM, adjacent text nodes are merged.
 - Text nodes cannot be assigned a React root ID.

This component is used to wrap strings in elements so that they can undergo
the same reconciliation that is applied to elements.

TODO: Investigate representing React components in the DOM with text nodes.
