Tooltip not showing for UnityEvents Tooltip attribute

[vlab22]

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;

public class SimpleWithUnityEvent : MonoBehaviour
{
    [SerializeField, Tooltip("Event without parameters")] // Tooltip not working
    private UnityEvent _onSomethingHappened;

    [Tooltip("Event with GameObject parameter"), SerializeField] // Tooltip not working
    private UnityEvent<GameObject> _onWithObject;

    [SerializeField, Tooltip("Some integer value")] // Works
    int _someValue = 42;

    [SerializeField, Tooltip("A list of strings")] // Works
    private List<string> _someStrings;
}

If we remove MyBox package, the tooltips will work.

Specs:

• Unity 2022.3.62f2
• Win11
• Single Display 1920x1080 (Scale 100%)
