Issue Summary

On page using the legacy editor, if a user has inherited permissions to the page which s being reflected as Url instead of the title, the text title for the link will be automatically changed to /wiki/spaces/<spacekey>/pages/<pageID> and published automatically with it, instead of just showing this URL for the user, but it actually changes the text in the page, and users who have permissions to see the page, will see the title /wiki/spaces/<spacekey>/pages/<pageID>, causing confusion among the users.

Steps to Reproduce

1. Create a new page using the legacy editor
2. Insert a Page Link from another space
3. Publish the page
4. Make sure to have inherited permissions on the page where the page link was from
5. Refresh the published page

Screenshot for reference:

The issue seems to be specifically for the pages where the permissions are inherited.

Please note issue is intermittently reproducible under the customer's environment

Expected Results

The page title doesn't change for the users who have inherited permission to see a page linked, the URL link title changes to /wiki/spaces/

Actual Results

The page title changes if the user has inherited permission to see a page linked, the URL link title changes to /wiki/spaces/ where the URL is, the title is also not shown, only the pattern /wiki/spaces/<spacekey>/pages/<pageID> appears instead.

Workaround

To avoid it to happen, you can click on the link, click on edit in the link macro and insert the page title and publish. You can also convert the page to the new editor.
