I would like to generate a dynamic preview image for a macro in Confluence Connect. For this I need to have the possibility to get the macro content. According to the Connect Doc (https://developer.atlassian.com/static/connect/docs/modules/fragment/image-placeholder.html), the type for "imagePlaceholder" is "uri" instead of "uri-template", which results in an error being thrown when I use an URL like this to get the necessary macro information:

                 "imagePlaceholder": {
                    "width": 100,
                    "height": 25,
                    "url": "/preview?pageId={page.id}&pageVersion={page.version}&macroHash={macro.hash}",
                    "applyChrome": true
                  }

Any chance to get this changed to "uri-template" soon? This would allow a very nice user experience because the user does not need to go into the macro browser to see a preview of the content...
