osm

In the event payload the return type of layer is `L.Layer? so it needs to be casted to the Layer-Type.

layer.on('pm:edit', (e) => {
  if(e.shape === 'Polygon'){
     (e.layer as Polygon).getLatLngs();
  }
});

I think following should work too: (But not tested)

layer.on('pm:edit', (e) => {
  if(e.layer instanceof L.Polygon){
     (e.layer as Polygon).getLatLngs();
  }

Describe the bug
adm0_{l,r} tags show up on regular boundaries at z5 but the demo shows them at z4 on maritime boundaries derived from OSM data and not natural earth.

To Reproduce
Steps to reproduce the behavior:

1. Generate a world map with basemap profile including Z4
2. Inspect the generated tiles

**Expected beh

I suggest that [landuse=basin] may be rendered with flat water-blue, and no strange green icon.

Hi,

I have a huge collection of photos, and think it would be nice to get back to the last position in image list when reopening the app, some kind of session restore in a way.
Thanks a lot for your work

e.g. as per https://wiki.openstreetmap.org/wiki/API_v0.6#Details_of_multiple_users but idiomatic to how the codebase already works.
