[SOLVED] Relationship attribute is bugged

Hello! I cannot select any "related collection" in the relationship attribute modal, and everytime i try to scroll the modal closes.

TL;DR

The user reported a bug with the relationship attribute, but it has been solved. The issue was that it didn't work on Firefox dev web browser, but it worked on Opera GX. The user apologized for the inconvenience.

This is how the modal looks when i try to open the listbox. You can see in the back that, in fact, i do have multiple collections, hope for a fix soon. Thank you for your time!
