"Add Component" search and selection is broken when inspecting a buildconfiguration file

Reproduction steps:
1. Open the attached project “IN-9101_TestDOTS.zip”
2. Select “Assets/Build/Default” in the Project window
3. Select “Add Component” in the Inspector window
4. Try type anything in the Search field
5. Try to select any elements of the list

Expected result: The list is filtered in step 4, child elements are listed in step 5
Actual result: The search doesn’t work, the list doesn’t refresh to show child elements

Reproducible with: 2021.3.8f1, 2022.1.15f1
Not reproducible with: 2020.3.39f1, 2021.3.9f1
Could not test with: 2022.2.0b7, 2023.1.0a9 (buildconfiguration isn’t compiling)

Note: It’s still possible to select one of the child elements by clicking multiple times (eg. click “Global” twice)
