How to reproduce:
1. Open the “AudioClipReplaceBug.zip“ project
2. Open the “SampleScene“
3. In the Hierarchy, select the “Audio1“ GameObject, and then in the Inspector, observe the Audio Clip in the Test Script Component
4. In the Hierarchy, select the “Audio2“ GameObject, and then in the Inspector, observe the Audio Clip in the Test Script Component (it is different from the “Audio1” GameObject)
5. Select both GameObjects in the Hierarchy
6. Repeat steps 3-4

Expected result: Both Audio Clip references are different
Actual result: Both Audio Clip references are the same

Reproducible in: 2022.3.62f1, 6000.0.0b16, 6000.0.48f1, 6000.1.3f1, 6000.2.0a10
Not reproducible in: 2021.3.51f1, 6000.0.0b15

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- Not reproducible with the default Button’s OnClick events (or likely any other default events)
- Reproducible with other types of objects as well, but not the default types (int, float, bool, string, etc.)
- Usually the references change to the first selected GameObject’s reference
- Afterward the scene becomes dirty and the change can be undone
