I followed the example here in the docs:
https://docs.developers.optimizely.com/content-management-system/docs/example-extending-hyperlink-editor-descriptor
If I set "Site relative link" to: /blog and then Publish the content. When I edit the hyperlink, "Site relative link" is no longer populated an instead "Page" is selected and the Blog page is listed.
Is this expected behavior? What is making my links change in the editor?
