Content.*/page.* context variables are not provided in dialog url

Confluence Development Confluence Cloud
1

According to Confluence Cloud Developer page
https://developer.atlassian.com/cloud/confluence/context-parameters/

following context variables are supported: {context.id}, {space.id}

But following code in atlassian-connect.json
“url”: “/cpa-dialog?space={space.id}&pageId={content.id}&spaceKey={space.key}”

results in this url:
“cpa-dialog?space=&pageId=&spaceKey=&xdm_e=…”

As you can see, context parameters are blank for dialog.
Attaching atlassian-connect.json to reproduce the issues.

Is it somehow possible to determine id of the Confluence page that opened the dialog?

modules:{  
   webItems:[  
      {  
         location:"system.content.action/modify",
         weight:200,
         context:"product",
         target:{  
            type:"dialogmodule",
            options:{  
               key:"cpa-dialog"
            }
         },
         name:{  
            value:"==OPEN DIALOG=="
         },
         key:"cpa-menu-item",
         conditions:[  
            {  
               condition:"user_is_logged_in"
            }
         ]
      }
   ],
   dialogs:[  
      {  
         url:"/cpa-dialog?space={space.id}&pageId={content.id}&spaceKey={space.key}",
         options:{  
            chrome:false,
            width:"7680px",
            height:"4320px",
            header:{  
               value:"Confluence Dialog Title"
            },
            conditions:[  
               {  
                  condition:"user_is_logged_in"
               }
            ]
         },
         key:"cpa-dialog"
      }
   ]
}

My team has also noticed a problem with a missing context parameter. We have discovered that the space.key context param is missing in Page History view for an old page version.

space.key is supposed to be available for urls in descriptors:
https://developer.atlassian.com/cloud/confluence/modules/static-content-macro/

We have an open ticket for the issue. Atlassian if you are watching can you have someone look at DEVHELP-4145? It may have fallen through the cracks because it is a month old with no response.

Thanks!
