PFA patch to fix the issue of jsonb type rendering issue in runtime. RM#1404
I'm not convinced this is a good fix for a couple of reasons:
1) You're only applying the fix if we're running in the runtime. The runtime uses the Webkit engine just as Safari and Chrome do, so I'm more inclined to believe this is a version specific issue, rather than something that is definitely confined to the runtime.
2) What if the user has JSON data in a json field? Or worse, a text field?
I wonder if we could/should mark the contents of all text fields as CDATA to prevent the browser trying to do anything with them.
