Incorrect warning "Water area inside water area" when natural=water / natural=wetland inside natural=coastline

[rhys.macdonald@…]

What steps will reproduce the problem?

1. Create a closed way, tagged with natural=coastline with counter-clockwise direction.
2. Create another closed way, instead tagged with natural=water or natural=wetland, contained entirely within the coastline.
3. Run the validator.

What is the expected result?

No warnings occur.

What happens instead?

"Water area inside water area" warning is triggered.

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

This situation occurs commonly when adding lakes or wetlands to islands. This is valid tagging, so the validator shouldn't give any warnings for this.

According to the wiki, ​Where is the coastline, natural=wetland can also be under the common high water mark, e.g. inside water. Maybe better exclude it completely?
