V8 requires snapshot_blob.bin as you found out. To avoid confusion, `use_v8_context_snapshot` refers to a custom snapshot for chromium, which is slightly different from the default snapshot (it contains a few addtl things).
So in your case, I'd suggest using `use_v8_context_snapshot = false`, while still properly installing snapshot_blob.bin.
