Steps to reproduce:
- Add a new page
- Add a Web Content Display portlet to a page
- Add a new Basic WC article through the portlet
- After publishing, Click Configuration > Edit Web Content
- Make some edit to the article > Publish
The iframe will close, and the page/portlet will refresh with the edits.
The article publishes, but the page loads in the iframe, and the User can navigate around in an iframe. See attached gif.
