Polylines/Polygons not responding to visible/editable changes

[markmssd]

This is an old issue which was resolved in #1255, but it seems to have been reopened. I am using the latest version (v2.3.2) with this code:

    <ui-gmap-polygons
            idKey="'id'"
            models="buildings"

            path="'polygon'"
            stroke="buildings.options.polygons.stroke"
            clickable="buildings.options.polygons.clickable"
            editable="'isEditable'"
            visible="'isVisible'"
            events="events.polygonEvents"

            fill="buildings.options.polygons.fill">
    </ui-gmap-polygons>

However, I am not able to get individual polygons to show/hide (via 'visible') or to individually edit them (via 'editable').

P.S: It does work with a global variable as editable="areEditable".
