A Script Component that has a serialized custom class is not detecting changes in the first boolean variable when entering the Play mode with the Script Components GameObject opened in the Inspector

How to reproduce:
1. Open the “SerializibleBug“ project
2. Open the “SampleScene“
3. Open the “Testing“ GameObject in the Inspector
4. Enter the Play mode
5. Observe the Console window with the Collapse option
6. In the “Test“ Script Component drop-down the “Unit“ array and toggle on the “Boolean 1“ check box
7. Observe the Console window with the Collapse option

Expected result: When only the “Boolean 1“ check box is toggled on a message “1 True; 2 False; 3 False“ is displayed in the Console window
Actual result: When only the “Boolean 1“ check box is toggled on a message “1 False; 2 False; 3 False“ is displayed in the Console window

Not reproducible with: 2021.3.33f1, 2022.3.14f1, 2023.2.0a17

Reproducible on: macOS 13.5.2 (Intel)

Note: The issue is only reproducible when entering the Play mode with “Testing“ GameObject already open in the Inspector
