When inspecting near this park, an enclosing feature of type "residential area" is found covering most of the city "Grimma".
However, the feature is tagged as multipolygon, and it looks like it is somehow "inverted": The park is highlighted as residential area, but the rest of Grimma is not.

Clicking anywhere else in the southern part of Grimma (were one would expect an enclosing feature "residential area").

Is this a mapping error, or am I missing something?
