How to reproduce:
1. Create a new Unity project
2. Install the Memory Profiler package
3. Open Memory Profiler window
4. Capture a memory snapshot twice
5. Open both of the snapshots
6. Click Diff at the bottom of the Memory Profiler window
7. Change the view drop-down to 'Memory Map Diff'

Expected result: Labels of the same snapshots labels are the same in different Memory Profiler window places
Actual result: Labels of the same snapshots labels do not match in different Memory Profiler window places

Reproducible with: 2018.4.27f1, 2019.4.11f1, 2020.1.6f1, 2020.2.0b3

Reproducible with package versions: 0.1.0-preview.2, 0.2.5-preview.1
Could not test with package versions: 0.1.0-preview.1 (Memory profiler window layout is different)
