Description
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:

Research direction
Reproduce the dtslint failure in the DefinitelyTyped types/iobroker definitions at lines 332 and 336 using TypeScript 4.7, then inspect the $ExpectType handling. Compare its output with other tested TypeScript versions and IntelliSense. Done means the checks preserve the ioBroker namespace and no longer report Object | null for those expectations.
