Steps to reproduce:

1.Click on the edit button
2.Click on a link and click on the link insertion icon.
3.Without making any change just close the link inspector

The "Save Page" button becomes active though if you review the changes it will say that this revision matches the lastest version of the page.

Expected Result:
If there is not modification in the content it is probably better to keep the "Save Changes" button inactive.
