(Ibexa Experience v3.3.19 or later)

Steps to reproduce:

Scenario:

• assume having 2 Content Objects: main-content & related-content
• assume 2 Users: admin & non-admin
• related-content is related to main-content through an ezobjectrelation Field.
• non-admin can read/edit/publish main-content and has no permissions on related-content.
• admin publishes a new version of main-content with a relation to related-content
• non-admin edits main-content and tries to publish

Result:

Publishing fails showing the error Content with identifier XX is not a valid relation target
(Error is thrown by Ibexa\Core\Repository\Validator\TargetContentValidator )

Expected:

Publishing should succeed as non-admin is not seeing or changing related-content.
(This was the actual behaviour until v3.3.18)

Note:

Change was introduced to fix https://issues.ibexa.co/browse/IBX-1669 (see https://github.com/ezsystems/ezpublish-kernel/pull/3131)
