## Description

### Steps to reproduce

1.  Configure an OpenProject instance (A) to integrate with an XWiki
    
2.  Configure a second OpenProject instance (B) to integrate with the same XWiki
    
3.  Create work packages with the same (numeric) ID on both OP instances
    
4.  Link the work package on A to a page in XWiki
    
5.  Check the work package references in B
    

### What is the buggy behavior?

*   The second OpenProject instance shows a wiki page reference to its own work package, even though it has never been linked
    

### What is the expected behavior?

*   ID collisions across two OP instances should not result in a link being shown
    

### Technical note

This happens due to us filtering for `withInstance=<uuid>`, when XWiki expects `instance=<uuid>`
