I am using umbraco version 4.9.0 and trying to add video javascript code and when it saves it will add CDATA tag in HTML source. It is adding this HTML source multiple times so video doesn't show in frontend.

We are adding below script in RTE :

<script type="text/javascript" src="/test.js"></script>
<script type="text/javascript">
KV.widget({
"guid": "FrIjfhvo316",
"type": "featured",
"hideEmbedButton": true,
"hideDownloadButton": true,
"width": 550
});
</script>

After saving this content RTE each time CDATA will be appended, so it will look like as below :

<script type="text/javascript" src="/test.js"></script>
<script type="text/javascript">// <![CDATA[
CDATAOPENTAG-->
CDATAOPENTAG-->
CDATAOPENTAG-->

KV.widget({
"guid": "FrIjfhvo316",
"type": "featured",
"hideEmbedButton": true,
"hideDownloadButton": true,
"width": 550
});
// <!--CDATACLOSETAG
// <!--CDATACLOSETAG
// <!--CDATACLOSETAG
// <!--CDATACLOSETAG
// ]]></script>

Please advise
