How to reproduce:
1. Open the attached “rootbug.zip“ project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Enter Play Mode
4. Press the “Add“ button in the Game view

Expected result: The ScrollView expands when the elements are added
Actual result: The Scrollview doesn’t expand when the elements are added

Reproducible with: 2021.3.35f1, 2022.3.20f1, 2023.2.11f1, 2023.3.0b8

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

Notes:
- Also reproducible in Player
- The ScrollView expands if the Aspect is changed to fit more ScrollView elements onto the screen at once (when this is done, the ScrollView expands to show all the added elements, but the ScrollView doesn’t keep expanding if even more elements are added)
- Thos also occurs in project tab of Library pane in UI builder. Scrolling works only after collapsing/expanding folder.
