Can not find city with country subordination

[Gorynych]

Describe the bug
Can not find Kyiv, Ukraine using widget. It exists in countries-states-cities-database, but probably the issue is that it's a city at the level of state.

To Reproduce
Steps to reproduce the behavior:

1. Search for Ukraine in country field
2. Search for Kyiv in state field
3. There will be no Kyiv in states result, just Kyivska oblast
4. If select Kyivska oblast - there will be Kyiv as a capitol also

Expected behavior
Kyiv should be found either on the level of state inside Ukraine country, or on the level of city under Ukraine -> Kyivska oblast state.
