When <div> elements contain non-inline HTML elements, they and their styles are removed on import.
Input:
<div style="margin-left: 200px;">
<ol>
<li>Item 1</li>
<li>Item 2</li>
</ol>
</div>
Output:
<ol style="list-style-type: decimal;">
<li value="1"><span>Item 1</span></li>
<li value="2"><span>Item 2</span></li>
</ol>
Workaround: Set the style properties to the inner elements. They will not disappear.
