$ExpectType ignoring namespace in TS4.7

[AlCalzone]

I'm working on the type definitions for https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/iobroker and while doing so, I'm stumbling over a check error where dtslint with TS4.7 seems to ignore the namespace of a type:

ERROR: 332:5  expect  TypeScript@4.7 expected type to be:
  ioBroker.Object | null
got:
  Object | null
ERROR: 336:5  expect  TypeScript@4.7 expected type to be:
  ioBroker.Object | null
got:
  Object | null

All other tested TS version seem to work fine. Even IntelliSense on TS4.7 shows the correct type:
