Tracing is resulting in orphaned traces

[josephp27]

Hi, no matter what I try, I cannot get the traces to not create orphaned traces. I currently have a multi-agent system where there is a supervisor that has tools and subagents (that also have tools).

Agent	Trace ID	Expected
supervisor	0xb32dfdde...	✅ Root
agent1	0x4e64db01...	❌ Should have parent and same trace as supervisor
agent2	0x0bfd5184...	❌ Should have parent and same trace as supervisor
agent3	0x3c85fadd...	❌ Should have parent and same trace as supervisor

What's interesting is that the separate trace ids i look into will show tool executions properly. it seems to only be happening on the first layer from supervisor -> subagents/tools as far as i can tell

Tried on ADK Version 1.23.0 AND 1.16.0

This seems similar to this one that's happening in go: google/adk-go#439

Thanks!
