Comparing field with another field of different type

[orangedeus]

Hello.
I'm currently upgrading code from 4.10.0 to 6.x.x. Previously, comparison between select and multiselect fields was possible somehow e.g. select var any in multiselect var. This is the type config for both:

multiselect: {
    defaultOperator: "multiselect_any",
    widgets: {
        multiselect: {
            operators: [
                "multiselect_any",
                "multiselect_not_any",
                "multiselect_equals",
                "multiselect_not_equals",
                "is_null",
                "is_not_null",
            ]
        }
    }
},
select: {
    mainWidget: "select",
    defaultOperator: "select_equals",
    widgets: {
        select: {
            operators: [
                "select_equals",
                "select_not_equals",
                "is_null",
                "is_not_null",
            ],
            widgetProps: {
                customProps: {
                     showSearch: true,
                }
            }
        },
        multiselect: {
             operators: [
                  "select_any_in",
                  "select_not_any_in",
                  "is_null",
                  "is_not_null"
             ]
        }
    }
}

The valueSources in field has also been set to ["value", "field"]. In any case the behavior (or the default ones) seems to have changed upon upgrading. Is this still possible to implement?
