Rule: Variables and functions should not be redeclared #16 false positive

[janv8000]

I want to report a bug.

SonarTS version: SonarCloud

Rule key: typescript:S2814

Reproducer

declare namespace Company.Product.WebApi.Features.Resource.GetResource.GetResource {
    interface Request {
        type: ResourceType;
    }
    interface Response {
        result: number;
    }
}

Rule message: 'GetResource' is already defined.

Expected behavior

Should not warn.
