*Steps to reproduce:*
# Create a new URP Project.
# Import attached TabUXML.uxml or create a UI Document with 3 tabs using Tabs nested inside TabView.
# In the UI Document Hierarchy, move Tab 1 to between Tab 2 and Tab 3.

*Actual results:* Tab order is 2, 3, 1. The moved tab will always go to the end of the tabs.

*Expected results:* Tab order is 2, 1, 3. The moved tab should match its position in hierarchy.

*Reproducible with versions:* 6000.1.0a6, 6000.0.29f1

*Can’t test with versions:* 2022.3.52f1, 2021.3.45f1 - no Tab/TabView available.

*Tested on (OS):* MacOS 12.7.6

*Notes:*
* Pressing Ctrl+S will set this to the expected result. You may not want to save until you are happy with your changes because of UUM-87092.
* Have not thoroughly regression tested this as it seems to be a new feature. Please contact the ticket reporter if regression testing will be useful.
