Hi there. A parking lot should be mapped as a contiguous area (see One feature, one OSM element) as much as possible. You can include in the area parking aisles and footways between parking spaces. Any greenery such as grass strips or trees can also be included within the parking area.

Individual parking rows should not be mapped as separate parking areas.

Please see https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dparking

I've noticed this issue in changeset #1176912856 and #136427303 as well.

Please let me know if you have any questions, to let me know if I'm missing something, or if you need any help in correcting this.

(Otherwise, the standard method to draw parking of a complex size - ones that consists of disjointed areas, or because the area consists of multiple disjunct parts, or has holes is to use multipolygons.)
