Islet size computed wrong

[Jojo4u]

What steps will reproduce the problem?

1. File -> Download object ... -> ​https://www.openstreetmap.org/way/308481263
2. Run Validator

What is the expected result?

The feature has an area 1700m², well below the 1 km² for place=island. No warning should be displayed.

What happens instead?

"place=islet on large area, use place=island instead" warning is displayed.

Please provide any additional information below. Attach a screenshot if possible.

Probably the areasize comparison of place=islet is botched, a km² is one million m²!

In 10328/josm:

fix #12916, see #12496 - fix islet/island size warning

User name obfuscation is a bit overzealous here. ;-)
