EditorGUI.GetPropertyHeight does some unwanted side effects?

I wrote this useless drawer that is supposed to do nothing

 [CustomPropertyDrawer(typeof(DoesNothingAttribute))]
 public class DoesNothingDrawer : PropertyDrawer
 {
     public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
     {
         // float propHeight = EditorGUI.GetPropertyHeight(property, label);
         EditorGUI.PropertyField(position, property, label);
     }
 
     public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
     {
         float height = EditorGUI.GetPropertyHeight(property, label);
         return height;
     }
 }

This works as it was meant - does nothing, just draws the property

If I uncomment the line float propHeight = EditorGUI.GetPropertyHeight(property, label); which must not affect any other stuff because it's just a getter I get

What is going on? Is it my fault or unity's one?

UPD
Me and my mate figured out that this doesn't apply to 2019.4.18f1
The same code behaves differently on these two versions
Someone from unity team had broken the GUI code
