Keep isochrone polygon on map style change #4

Open havardl opened 4 years ago

havardl commented 4 years ago

When changing map style, the added isochrone polygon is lost. Need to make sure it persist across changes.

Seems that map.getSource(layerId) won't find the layer, so the layers might be removed on mapStyle change?
