Creating a Sub Scene in the Hierarchy V2 creates a duplicate GameObject under the main scene

Hierarchy V2

-

How to reproduce:
1. Create a new Unity project
2. Go to Window -> Package Management -> Package Manager -> Unity Registry -> ECS -> Install
3. In the Hierarchy, right-click on the "SampleScene" header -> New Empty Sub Scene
4. Observe the Hierarchy

Expected results: Only Sub Scene is created
Actual results: Sub Scene and a GameObject with the Sub Scene Component are both created

Reproducible with: 6000.3.6f1, 6000.4.0b5, 6000.5.0a5
Can't test with: 6000.0.66f1

Reproducible on: macOS Tahoe 26 (M1)
Not reproducible on: No other environment tested

Notes:
- Using the higher severity because duplicate GameObject introduces many situations where various errors are thrown
- Not reproducible in Hierarchy V1
