:doc command unfolds partial applications even when definition has documentation

Describe the bug

In the following snippet, :doc bar will explain foo instead of bar because bar is foo partially applied.

Steps To Reproduce

Save this to a file. In the repl, run :doc bar.

rec {
  /**
    foo
    */
  foo = _: _: {};
  
  /**
    bar
    */
  bar = foo {};
}

Expected behavior

Nix should not try to find the documentation of the underlying function. Or, alternatively, it should allow a pragma comment to specify whether it tries to find the documentation of the underlying function.
