How to reproduce:
1. Open the attached “array.zip” project
2. Open “SampleScene” Scene (Assets > Scenes)
3. In the Hierarchy window, select “Cube” GameObject
4. In the Inspector window, observe the Elements list of the “New Behaviour Script” Component

Expected result: List elements are “None (GameObject)”
Actual result: List elements are “None (GameObject[])”

Reproducible with: 2021.3.36f1, 2022.3.21f1, 2023.2.13f1, 2023.3.0b10

Reproduced on: macOS 14.2.1 (Intel)
Not reproducible on: No other environment tested

Note: It is not reproducible if the advanced search engine is used and the filters are added by hand. Unfortunately, this does not allow to restrict the object selection, which could be defined by the query of the SearchContext attribute
