JsonElement as root of DialogViewController

[HeathHopkins]

When using a JsonElement as the top element in a DialogViewController, the JSON is not downloaded. The window is rendered with the supplied caption in the title bar, but other than that, the window is empty.

When I use a JsonElement as a child of a regular RootElement, everything works correctly. I'm new to MtD, so I may be missing something. I couldn't find a method that would force downloading the content.
