Research direction
Start by reproducing the reported filter behavior with maptalks v0.40.4 in Chrome using the supplied GeoJSON feature and expression. Trace the filter handling for ['>=', ['zoom'], ['number', ['get', 'z']]] and compare it with the verified Mapbox behavior. Done means the z value controls the display level without breaking the existing symbol settings.
