How to reproduce:
1. Open the attached Unity project ("repro_2021.2.0b15.zip")
2. Open Memory Profiler (Window -> Analysis -> Memory Profiler)
3. Unzip and import snapshot in Memory Profiler ("Snapshot-637686068250000860.snap.zip")
4. Click on the imported snapshot

Expected result: Snapshot opens, "ArgumentException: only positive float values are supported. found: 0" exception not thrown in Console.
Actual result: Snapshot fails to open, "ArgumentException: only positive float values are supported. found: 0" exception thrown in Console.

Reproducible with: 0.4.0-preview.1, 0.4.1-preview.1 (2019.4.31f1, 2020.3.19f1, 2021.1.24f1, 2021.2.0b15, 2022.1.0a11)
