Current Behaviour

• While adding a text to link with another internal link ( from same space) gives warning that it is pointing to different site.

Use case 1

• If text to link is added similar to www.facebook.com it prompts that its taking to different site.

Use case 2

• If the text to link is added from same space ( any random link from same space) , it still warns that its pointing to different site.

Suggestion

While we understand Confluence aims to inform users when the actual URL of a hyperlink differs from the displayed text. The warning is still misleading.
Simplify and show more meaningful warning for better user experience.
