Notes:
- Simply increasing CPU load did not reproduce this issue (e.g., writing a large number of Debug.Log statements)
- The issue can be reproduced reliably by manually invoking System.GC.Collect
- In the provided sample scene, a script calls System.GC.Collect once per second to reproduce the issue
