Styling doesn't apply when referencing elements and all their parents in the USS file Selector

Unity: UI Toolkit Controls

As Designed

2023.2.X

2023.1.X

2022.3.X

This is by design as the ancestor combinator ">" checks for the "logical" parent of an element (element.parent), not the "physical" parent (element.hierarchy.parent). In other words, the logical hierarchy goes through the ".contentContainer" and not the ".hierarchy".

How to reproduce:
1. Open the attached “Temp.zip“ project
2. Open the “SampleScene“ Scene
3. Observe the Game view

Expected result: The ScrollView has a border that is red on the left
Actual result: The ScrollView has a border that is green on the left

Reproducible with: 2022.3.6f1, 2023.1.6f1, 2023.2.0b2
Can’t test with: 2021.3.29f1 (Errors in the Console)

Reproduced on: macOS 13.4.1 (Intel), Windows 10 (by reporter)

Note: Also reproducible in Player
