Repro Code

declare namespace A.B {
  const y: string;
}

/** @deprecated */
declare namespace A.C {
  const z: string;
}

console.log(A.B.y);

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/no-deprecated": "error"
  }
}

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}

Expected Result

No lint errors on the line console.log(A.B.y), because none of the elements A, A.B, or A.B.y are marked @deprecated.

Actual Result

A @typescript-eslint/no-deprecated lint error appears on that line:

`A` is deprecated. 10:13 - 10:14

Additional Info

A real-world example of this is in the @types/chrome package, which provides typing for browser-specific APIs exposed by Chrome for use in Chrome Apps and Chrome Extensions. There are a bunch of specific APIs that are deprecated, such as:

/**
 * @deprecated Part of the deprecated Chrome Apps platform
 */
declare namespace chrome.socket {
  // ...
}

But this results in the linter raising a @typescript-eslint/no-deprecated at every usage site of chrome (not just chrome.socket - also other things like chrome.tabs, chrome.runtime, etc, which aren't deprecated).
