Filter relationship collections does not show all collections

[GermanJablo]

Describe the Bug

The changes I made to _community to get the repro can be seen here:
main...filter-pagination-bug

Not all users are shown in the select, which should be users 1 to 1500.

Also, requests seem to increment the pagination parameter by +1 every time an option is chosen that was pre-selected with the keyboard.
