Reproduction steps:
1. Open project “My project (11).zip”
2. Open “SampleScene”
3. Select “Triangle” GameObject through the Hierarchy
4. Under “Relative Joint 2D” enable “Auto Configuration Offset” through the Inspector
5. Observe the “Angular Offset” property
Expected result: the value displayed is 90 - the same as the “Triangle” GameObject Rotation on the Z axis
Actual result: the value displayed is 1.570796
Reproducible with: 2021.3.28f1, 2022.3.5f1, 2023.1.4f1, 2023.2.0a23
Reproducible on: macOS Ventura 13.2.1 (Intel), Windows 10 (by the reporter)
Notes:
- Although the value displayed is in radians, Angular Offset itself uses degrees (observe through Scene view)
- 1.570796 radians is 90 degrees
