Editor Pane not displaying associated domain resource definition

Input Criteria:  editor in split mode, viewing API, API references domain file

Acceptance criteria:  view associated domain resource definition in editor view

Bug: when viewing an API, clicking the 'arrow' in the right hand UI pane (while in split view) on a domain resource.  Standard swaggerUI practice is to move the editor view to show the resource definition.    When on swaggerHub UI,  clicking the resource arrow does not display the associated resource definition.  The editor page jumps, but only within the API definition file. 

I would expect the editor page to change to the resource anchor within the domain (swapping api code view for domain code view) or I would expect a new editor window/tab to open with the cursor positioned at the resource anchor.
