 * with boilerplate code for react component). More information on the
 * exact problem can be found here -
 * https://github.com/facebook/draft-js/commit/07892ba479bd4dfc6afd1e0ed179aaf51cd138b1
 *
 * 2. intended to handle spellcheck and autocorrect changes,
 * which occur in the DOM natively without any opportunity to observe or
 * interpret the changes before they occur.
 *
 * The `input` event fires in contentEditable elements reliably for non-IE
 * browsers, immediately after changes occur to the editor DOM. Since our other
 * handlers override or otherwise handle cover other varieties of text input,
 * the DOM state should match the model in all controlled input cases. Thus,
 * when an `input` change leads to a DOM/model mismatch, the change should be
 * due to a spellcheck change, and we can incorporate it into our model.
