Filtering on multiple labels at the same time

Despite having the “Require all filters to be true for a task to show up” checkbox checked, when I add labels to the filter, tasks that have any of the labels show up. I would have expected only tasks with all of the labels to show up.

I think this is worth another option in the filter pop-up, because I can definitely see use cases for both.

This sounds like a bug. There are plans to rework how filters work in general which would fix that as well.
