In Post Ads - stripping part od ad code for site admins

Hi there.

I'm seeing and issue that I'm not sure how to resolve.

In our multisite, the super admin can create In Post Ads with no issues.

But, Site Administrators cannot - the code is being mangled.

For example, If I paste in the following Google Adsense code, the code in the red box is being stripped off when I save the post. (This only happens to site administrators - not super admin)

After some research, it looks like this may be related to "unfiltered_html" WP capability?

Is there a way to make this work without giving everyone that capability out right. That's just scary...
