How to reproduce:
1. Open the attached (Standalone Profiler Issue.zip) project
2. Open the Profiler Window (Window -> Analysis -> Profiler)
3. Enter the PlayMode -> Pause it after few seconds
4. Open the Standalone Profiler (Window -> Analysis -> Profiler(Standalone Process))
5. Once the Standalone Profiler has opened - close it
6. Enter the PlayMode -> observe the Profiler

Expected results: Profiler performance stays the same as it was before opening and closing the Standalone Profiler
Actual results: Profiler performance drops significantly when opening and closing the Standalone Profiler (see Performance.png)

Reproducible with: 2019.3.14f1, 2020.1.0b9, 2020.2.0a11

Notes:
- Could not test on 2018.4 and lower, because Standalone Profiler does not exist in these versions
