Limit list to selected items ['expose']['reduce'] don't care about the operator

If this problem was discovered on a version of Drupal that is not 11.x, add that information in the issue summary and leave the version at 11.x. In Drupal core changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → . Also mentioned on the version → section of the list of issue fields documentation. Thanks.

If I understand you correctly, what you expect to see is not how it's supposed to work. The operator is only for the resulting query, not for which options are shown in the filter, so if you limit the options it will always show the options you checked, not the reverse of what you checked.

Am I understanding your issue correctly?
