Description

Hello,
When using a tile with GeomType = 0 (UNKNOWN), L.vectorGrid.protobuf says

Leaflet.VectorGrid.js:113 Uncaught (in promise) TypeError: Cannot read property 'render' of undefined

But I think L.vectorGrid.protobuf should regard it as no content as MapboxGL does.

Research direction

Start at Leaflet.VectorGrid.js:113 and reproduce the error with a tile whose GeomType is 0 (UNKNOWN). Trace the protobuf vector-grid rendering path and verify that UNKNOWN geometry is treated as having no content, without attempting to call render on an undefined renderer.
