Additional context

First edit submit click correctly becomes

<div class="se-component se-image-container __se__float-right" contenteditable="false">
  <figure style="margin: auto;">
    <a href="http://suneditor.com/" alt="http://suneditor.com/" data-image-link="image"><img src="http://suneditor.com/docs/cat.jpg" data-align="right" alt="Tabby" data-rotate="" data-proportion="false" origin-size="640,426" data-origin="640,426" data-file-name="cat.jpg" data-file-size="0" data-size="," data-percentage="auto,auto" style="" data-index="0" data-rotatex="" data-rotatey="" data-image-link="http://suneditor.com/">
    </a>
    <figcaption contenteditable="true" style="margin-top: 0px;">
      <p>Insert description</p>
    </figcaption>
  </figure>
</div>

Second submit click makes an error

<div class="se-component se-image-container __se__float-right" contenteditable="false">
  <figure style="margin: auto;">
    <a href="http://suneditor.com/" alt="http://suneditor.com/" data-image-link="image"></a>
    <a href="http://suneditor.com/" alt="http://suneditor.com/" data-image-link="image">
<img src="http://suneditor.com/docs/cat.jpg" data-align="right" alt="Tabby" data-rotate="" data-proportion="false" origin-size="640,426" data-origin="640,426" data-file-name="cat.jpg" data-file-size="0" data-size="," data-percentage="auto,auto" style="" data-index="0" data-rotatex="" data-rotatey="" data-image-link="http://suneditor.com/">
    </a>
    <figcaption contenteditable="true" style="margin-top: 0px;">
      <p>Insert description</p>
    </figcaption>
  </figure>
</div>

Third submit click compounds the error

<div class="se-component se-image-container __se__float-right" contenteditable="false">
  <figure style="margin: auto;">
    <a href="http://suneditor.com/" alt="http://suneditor.com/" data-image-link="image"></a>
    <a href="http://suneditor.com/" alt="http://suneditor.com/" data-image-link="image"></a>
    <a href="http://suneditor.com/" alt="http://suneditor.com/" data-image-link="image">
<img src="http://suneditor.com/docs/cat.jpg" data-align="right" alt="Tabby" data-rotate="" data-proportion="false" origin-size="640,426" data-origin="640,426" data-file-name="cat.jpg" data-file-size="0" data-size="," data-percentage="auto,auto" style="" data-index="0" data-rotatex="" data-rotatey="" data-image-link="http://suneditor.com/">
    </a>
    <figcaption contenteditable="true" style="margin-top: 0px;">
      <p>Insert description</p>
    </figcaption>
  </figure>
</div>
