I'm having this issue even with paragraphs =(

<Editor
  tag="pre"
  text={this.state.texto}
  onChange={this.handleChange}
  options={{toolbar: {buttons: ['bold', 'italic', 'underline','anchor', 'h1', 'h2', 'quote']}, 
  autoLink: true, 
  placeholder: {text: 'Conte sua hist\ória..'}}}
  />

Any idea why?

This is mainly caused by the the editor text which was passed to the parent component and then passed in as the changed property that result state change and ui update. I'll try to make a pr to fix this.

The same situation with orderedlist and unorderedlist
