We are trying to embed Instagram posts into a standard article using Instagram's standard embed code (not the Media plugin). However, when we embed the code it changes the correct code

<s-cript async src="https://www.joomlacontenteditor.net/www.instagram.com/embed.js"></s-cript>

to the following

<s-cript async="" type="text/javascript"></s-cript>

Which obviously breaks the post from embedding properly. We have Joomla's global config set to No Filtering for the desired user groups. Also, we have iframes allowed within JCE. What are we missing in terms of getting the script to not be removed. We do not have RsFirewall or Admin Tools installed, so neither of those components would be stripping the coding. Note that I have added the dash in the script so it doesn't trigger you firewall when submitting this post

Same here on my sites.
Version 2.8.16 RC2 fix that issue...

@Ryan,
The RC you provided fixed the issue - thank you!
