Inspector remembers [HideInInspector] variables

The inspector remembers values of variables that are set to be hidden in the Inspector which I think it should not do. My test script looks like this:

 class MyClass : MonoBehaviour
 {
     [HideInInspector]
     public string myText = "111";
 
     void Start()
     {
          Debug.Log("myText: " + myText);
     }
 }

Now I attach the script to a gameObject, run the project and get "myText: 111" in the console as expected.

Then I change the "111" in my script to something else i.e. "222", run the project again and still get "myText: 111" in the console.

Now I reset my Script component in the inspector, run the project once more and get the expected "myText: 222" in the console.

I would say this is a bug since [HideInInspector] should make unity to ignore the variable and not remember its current value. Or is this now intended behaviour?
