Steps to reproduce
- Add a widget page
- Navigate to the widget page
- In the top menu, click the "+" button to get the right-hand panel to add a Widget or Content
- Switch to the Content tab
- Choose to add a new Basic Web Content
- Fill in a title and publish
Expected behavior is that this adds a web content display portlet, the way it does in 7.2.x.
Actual behavior is that it doesn't do anything.
