Rich Snippets – Reviews Plugin blocks VideObject markup in Posts!

Hi, I use the Google Rich Snippets – Reviews Plugin by poer to display review microdata. Now I wanted to add this:

<div itemprop="video" itemscope itemtype="https://schema.org/VideoObject">
<h2><span itemprop="name">My Great Video</span></h2>

<meta itemprop="duration" content="T17M57S" />
<meta itemprop="thumbnailURL" content="https://i4.ytimg.com/vi/GCEPWfMTUZQ/mqdefault.jpg" />
<meta itemprop="embedURL" content="https://www.youtube.com/watch?v=GCEPWfMTUZQ" />
<meta itemprop="width" content="520" />
<meta itemprop="height" content="300" />
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000">
<param name="movie" value="https://www.mywebsite.com/my-video.swf">
<param name="quality" value="high">
<param name="play" value="true">
<embed src="https://www.youtube.com/watch?v=GCEPWfMTUZQ"type="application/x-shockwave-flash">
</embed>
</object>

<p><span itemprop="description">This video was made to illustrate...</span></p>
</div>

To embed a video and set the rich snippet for a video. It seems that the plugin blocks this because every time I save/refresh there is still the video but no microdata!

Can anybody help?
