How to reproduce:
1. Open the attached “IN-7226.zip” project
2. Open the “NegativeScrollTestWindow” (Window → Environment → NegativeScrollTestWindow)
3. Press the “break scroll” button

Expected result: The TreeView Binding is correctly aligned with the name
Actual result: The TreeView Binding is unaligned

Reproducible with: 2022.1.14f1, 2022.2.0b6, 2023.1.0a9
Couldn’t test with:
- 2020.3.39f1 (Error: Tuple must contain two elements)
- 2021.3.8f1 (Code not accessible due to protection level)

Reproduced on: macOS Monterey 12.0.1

Note:
- To reset alignment press the “unbreak scroll” button
- 2022.1 is always unaligned but numbering is correct
- 2023.1 is always unaligned and when “breaking” the negative numbering starts from -1 and not 0
