The empty new lines from RTF are imported as empty paragraphs in the editor and not rendered, i.e.

<p class="TelerikNormal" style="line-height: 16px;"> </p>
<p class="TelerikNormal" style="line-height: 16px;"> </p>
<p class="TelerikNormal" style="line-height: 16px;"> </p>
<p class="TelerikNormal" style="line-height: 16px;"> </p>
<p class="TelerikNormal" style="line-height: 16px;"> </p>


They should be rendered, because in other case this breaks the layout of the inserted document.
