| R1 | 'linked_place' : 'city', 'wikidata': 'Q1234' |
| R2 | 'wikidata': 'Q1234' |


Scenario: Boundaries without names inherit names from linked places
Given the 0.05 grid
| 1 | | 2 |
| | 9 | |
| 4 | | 3 |
Given the places
| osm | class | type | extra+wikidata | admin | geometry |
| R1 | boundary | administrative | 34 | 8 | (1,2,3,4,1) |
And the places
| osm | class | type | name+name |
| N9 | place | city | LabelPlace |
And the relations
| id | members |
| 1 | N9:label |
When importing
Then placex contains
| object | name+_place_name |
| R1 | LabelPlace |
