Hmm, what were your steps where it worked?<p>Undo and other text editing facilities aren&#x27;t completely nonfunctional, they just become broken and unpredictable. For example, these steps:<p>1. Load <a href="http:&#x2F;&#x2F;facebook.github.io&#x2F;draft-js&#x2F;" rel="nofollow">http:&#x2F;&#x2F;facebook.github.io&#x2F;draft-js&#x2F;</a>
2. Click in the text box
3. Type &#x27;hello&#x27; on the keyboard
4. Using the mouse, choose Edit -&gt; Undo<p>The text box will show &quot;h&quot; instead of being empty. Do you see this too?<p>Note that cmd-Z won&#x27;t reproduce this since the page tries to handle that itself to work around these bugs.
