Memory leak on CancellationTokens when using an AsyncInstantiateOperation

How to reproduce:

1. Open the attached “IN-147928“ Project
2. Open the “SampleScene” Scene (Assets/Scenes)
3. Enter Play mode
4. In the Hierarchy window, double click the "Leaker" GameObject
5. In the Inspector, open the Context menu of the “Leak Repro (Script)” Component (three dots) and select "Run"
6. Repeat step 5 a few times
7. Observe the “Before“ and “After“ used Memory amounts in the Console window

Actual result: After each “Run“, the Console shows that the used Memory “After“ the “Run“ is higher than “Before“
Expected result: Each “Run“ log in the Console shows the same used Memory in the “Before“ and “After” fields
