Issue with video alignment

[amolswnz]

Issue found in Elemental elements - Content Block

Add media from web - any video url. Select placement other than left Insert media. Placement is saved but the video stays left irrespective of the alignment.

Sample code

<div class="rightAlone ss-htmleditorfield-file embed" style="width: 480px;" data-url="https://www.youtube.com/watch?v=cLmCJKT5ssw" data-shortcode="embed">
  <img class="placeholder" src="https://i.ytimg.com/vi/cLmCJKT5ssw/hqdefault.jpg" width="480" height="270" />
</div>
