Writer doesn't seem work after resuming workflow

I hope I’m not doing anything wrong, but I want to stream custom events during my workflow execution and

writer.write()

writer.write()

seems to only work during initial workflow execution. After calling

resumeStreamVNext()

resumeStreamVNext()

, any

writer.write()

writer.write()

calls are silently ignored and don't emit events.

I pushed a simple reproduction repo here: https://github.com/simon-hv/mastra-writer-stream-reproduction

Thanks for your help!
