Not warning about open islands with coastline

[naoliv]

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

place=island should be used either on a single closed way or a multipolygon, not the way like in you example.osm file.

[naoliv]

That is why I am asking for a validator warning, so we can catch islands that are wrong.

A real example: this island ​https://www.openstreetmap.org/#map=15/-23.5418/-45.0677 was wrongly split in multiple ways with place=island, like this way ​https://www.openstreetmap.org/way/525742175/history

Since the ways also had natural=coastline, JOSM didn't give any warning about the wrong ways tagged with place=island

[Klumbumbus]

Yes, I was a bit confused.

In 13394/josm:

• fix #15648 - warn about unclosed ways with place=islands
• fix #15659, see #12043 - always display place=island and place=islet fill color (and name) independent from the place style setting. Regression of r8986.
