3. Enter Play mode
4. Observe the console
Actual result: Log claiming "Leak Detected : Persistent allocates 4 individual allocations."

Reproducible with: 2.6.0 (6000.0.0b11), 2.9.0 (6000.6.0b4)
Not reproducible with: 2.5.2 (6000.0.0b11)
Reproducible on: MacOS 26.5 (M1), Windows 11 (by reporter)
Not reproducible on: No other environments tested
Note: The Spline in the SampleScene is deliberately scaled non-uniformly, as this causes 100% repro rate. But it happens in cases where the SplineContainer and all parents are uniform
