Goes by priority, but allows for fields to be empty. This is important e.g. for models which are removed just from live, or just from draft. Also reacts to a field rename done in CMS module (62783c75).

/**
|
|
* Shows a previewable website state alongside its editable version in backend UI,
|
|
* typically a page. This allows CMS users to seamlessly switch between preview and
|
|
* edit mode in the same browser window. The preview panel is embedded in the layout
|
|
* of the backend UI, and loads its content via an iframe.
|
|
*
|
|
* The admin UI itself is collapsible, leaving most screen space to this panel.
|
|
*
|
|
* Relies on the server responses to indicate if a preview URL is available for the
|
|
* currently loaded admin interface. If no preview is available, the panel is "blocked"
|
|
* automatically.
|
|
*
|
|
* Internal links within the preview iframe trigger a refresh of the admin panel as well,
|
|
* while all external links are disabled (via JavaScript).
