SoapUI 5.4.0 XML tab don't display JSON content like 5.0.0

With the 5.0.0 version, when I receive a JSON response, I can show it in the XML tab. It's important for me because one json property of the message includes an HTML content. So I can copy and past this content easily in a text editor.

 

With the 5.4.0 version, the json response in displayed in the json tab solely. In the XML tab there's the message "The content you are trying to view cannot be viewed as XML".

 

Can I reproduce the 5.0.0 behavior with the 5.4.0 version ?
