Filtering the Roadmap by label "is one of" is not returning expected results

Summary

When filtering the Roadmap using a label filter by is one of (aka "OR"), the results return values that do not match any of the filter criteria.

Steps to reproduce

1. Navigate to the roadmaps view here
2. In the filter bar, enter: label is one of ~"group::product planning" and label is one of ~"group::project management"
3. Review the results and notice that there are results which do not include the aforementioned scoped labels (noting that the results also do not include descendants that may match the criteria)

Additional information

• The "is one of" feature was introduced in !110706 (merged) as epic lists and roadmap share the same filters implementation
• Notably, "is one of" works fine on epics list, example: https://gitlab.com/groups/gitlab-org/-/epics?state=opened&page=1&sort=start_date_desc&or[label_name][]=group::project+management&or[label_name][]=group::product+planning
