Background information
For the proposed design of T248123, the PCS JS should send an interaction event through the InteractionHandler when the user taps to show the collapsed page issues. When that event is received, the native apps will display a native modal view with HTML content.
What
Ensure older clients will continue to work when features such as these are added. Either utilize content-type profile versioning, a parameter to Page.setup(), or some other method.
Open questions
Will RESTBase keep multiple Content-Type profiles around for the same endpoint if a client requests an older version?
