Physics2D.Simulate(0) does not trigger OnTriggerEnter2D and OnTriggerExit2D when they were triggered once before

Physics2D

-

Reproduction steps:
1. Open the attached project "PhysicsSimulateBug.zip"
2. Open the Console Window
3. Enter Play Mode
4. Observe the Logs in the Console Window

Expected result: "Enter Trigger" and "Exit Trigger" should be logged in the Console after every enter and exit from the trigger when the Physics2D.Simulate(0) is called
Actual result: "Enter Trigger" and "Exit Trigger" are logged in the Console only once when the Physics2D.Simulate(0) is called

Reproducible with: 2019.4.39f1, 2020.3.34f1, 2021.3.3f1, 2022.1.1f1, 2022.2.0a8
Not reproducible with: 2022.2.0a9, 2022.2.0a14

Note: if the Physics2D.Simulate(Mathf.Epsilon) method is called, the OnTriggerEnter2D and OnTriggerExit2D Events are called every time, but using the Physics2D.Simulate(0) method these Events are called only one time each in total

  1. Resolution Note (fix version 2022.2):
