Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.

Reproduction steps:
1. Open the attached "PrefabInspectorDropdownReload.zip" project
2. Select "Assets/GameObject.prefab" to see its properties in the Inspector
3. In the “Polygon Collider 2D” Component click the “Points” dropdown (Unravel nested dropdowns if they're not visible as well)
4. Enter any number in the “Size” property (Paths>Size)
5. Press the “Enter” button on the keyboard

Expected results: The unraveled dropdowns are still visible
Actual results: Dropdowns collapse to the highest level (in these steps - to Points)

Reproducible with: 2022.3.9f1, 2022.3.19f1, 2023.2.7f1, 2023.3.0b4
Not reproducible with: 2021.3.34f1, 2022.3.8f1

Reproducible on: macOS 13.6.3 (Intel), Windows 11
Not reproducible on: no other environment tested

Note:
