Complain about boundary=administrative and landuse=residential tagged on the same area

[matkoniecz]

I think that suggesting to delete landuse=residential tag and mapping it properly, as a separate object would be desirable.

What steps will reproduce the problem?

Create closed way
Tag it with boundary=administrative and landuse=residential and admin_level=1
Run validator by clicking element

What is the expected result?

Validator complains about two distinct features tagged on the same area - violating ​https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element

Opened as result of ​gravitystorm/openstreetmap-carto#3664

What happens instead?

Nothing, such area is displayed as usual boundary=administartive.

Equivalent JOSM issue (implemented recently) is at https://josm.openstreetmap.de/ticket/17305
