Link integrity endpoint serves different result than the browser view

[pgrunewald]

When comparing link integrity on the Plone classic UI and Volto, I noticed a weird difference.

When having the following setup:

• page Add plone.restapi pkg with docs, tests and basic implementation of a read-only API. #1
• page CORS handling #2 (links to page Add plone.restapi pkg with docs, tests and basic implementation of a read-only API. #1)

When now trying to delete both pages, there should be no link breakage, since the pages references themselves. This is true for the classic UI, see screenshot:

Now compare this with Volto modal:

The Volto modal complains about a potential link breakage, which should not be there.

This was verified with Volto 17.0 and plone.restapi 8.37 and the Plone 6.1 coredev version.

@pgrunewald thanks for the bug report. We plan to work on this in the upcoming weeks for a client project. cc @jackahl @giuliaghisini.
