@color of method isn't merged to @color of the class

[tolk-vm]

Describe the bug
I have a class with @color and its method with another @color.
I expect the method to have both colors (in order class-color + method-color), but it works somehow differently.

To Reproduce
PHP code

/** @color controller */
class Controller {
  /** @color allow-model-call */
  static function act() {
    Model::act();
  }
}

/** @color model */
class Model {
  static function act() {}
}

palette.yaml

demo:
- controller model: restricted dependency
- controller allow-model-call model: ""

Expected behavior
No error (the second rule should be matched);

Actual behavior
An error (the first rule is matched)
BTW, if I add @color allow-model-call as a second color to the Controller class itself, everything works as expected. So, the problem is only in class+method case.
