Inspecting ShaderGraph in Debug mode results in ~150ms CPU Scripts Usage and ~1.5 MB GC Alloc per frame

How to reproduce:
1. Open the user’s attached “InspectorBug” project
2. Change the Inspector window mode to “Debug”
3. Select the “MyGraph” ShaderGraph in the Project Browser
4. Observe the CPU Usage in the Profiler

Expected result: CPU Usage time is ~5ms and ~230B GC Alloc per frame
Actual result: CPU Usage time is ~150ms and ~1.5MB GC Alloc per frame
