Issue Summary

When using a link macro, and selecting the Embed display view, the page will require authentication, if the link used is the page's tiny link (https://<instance>.atlassian.net/wiki/x/<code>)or page share link (https://<instance>.atlassian.net/l/cp/<code>). Even after authentication, the behavior will repeat and the pages won't be visible

Steps to Reproduce

1. Create a new page and publish it
2. Get the tiny URL for that page (^...>Advanced details>Page Information>Tiny link) or the page share link (Share>Copy link)
3. Create another page, and use the Link macro (/Link). Use the tiny/share link as URL, instead the page's full URL
4. Publish the page

Expected Results

The first page should be embedded in the second page, due the display view selected in the Link macro

Actual Results

The user gets a "You need to be logged in to view this page" on the embedded page, and even if they authenticate, the content will not be displayed and request authentication once again.

Workaround

Edit the page and change the Link macro URL to the full page URL, instead the tiny/share link.
