Steps to reproduce:

1. Create a new project using Universal 3D Template
2. Right-click in the Hierarchy > UI Toolkit > UI Document with Asset
3. Select the UI Document in the Hierarchy
4. Double-click on the Panel Settings asset
5. Change the "Render Mode" to "World Space"
6. Open the Source Asset file in UI Builder
7. Add 1-2 Labels to the Hierarchy in UI Builder and Save
8. Observe the Console

Actual results: "Internal: deleting an allocation that is older than its permitted lifetime of 4 frames (age = 5)" and "Internal: JobTempAlloc has allocations that are more than the maximum lifespan of 4 frames old - this is not allowed and likely a leak" warnings

Expected results: no warnings/leaks
