Bug (Case 1420597) Tooltip problems

Some [Tooltip] are misplaced and some [Tooltip] don't work at all.

Code (CSharp):

1. public class NewBehaviourScript : MonoBehaviour
2. {
3.     [Tooltip("This is an integer")] // tooltip is misplaced
4.     [SerializeField] int m_MyInt = 123;
5.  
6.     [Space]
7.     [Tooltip("Hello World")] // tooltip doesn't appear at all
8.     [SerializeField] VoidEvent m_MyEvent = new VoidEvent();
9.  
10.     [System.Serializable]
11.     class VoidEvent : UnityEngine.Events.UnityEvent { }
12. }

Actual
"My Int" tooltip is misplaced.
"My Event" doesn't show any tooltip.

Expected
"My Int" tooltip is displayed under mouse pointer.
"My Event" displays a tooltip when I place the mouse pointer on the "My Event" text.

 

QA replied that it's a known issue:

However, the issue only mentions "tooltips are not shown". It doesn't mention that tooltips are misplaced sometimes as well.
