15648	Not warning about open islands with coastline	naoliv	team	"Validate the attached example.
JOSM properly warns that an ""area style way is not closed""

Now select the two ways, add `natural=coastline` and validate again: we can't see any warning about the open island.

Unless I am missing some coastline feature, open islands/islets should give a warning even if we have `natural=coastline`
