`debuggingName` from Worker action is not used

[chr-stripe]

I could be doing something wrong in my interceptor, but it doesn't seem as though the debugging name used by WorkflowActions that handle the result of a Worker are bubbling up to the WorkflowInterceptor. I have some minimal reproducible example code below:

package com.stripe.reader.application

import com.squareup.workflow1.BaseRenderContext
import com.squareup.workflow1.Worker
import com.squareup.workflow1.Workflow
import com.squareup.workflow1.WorkflowAction
import com.squareup.workflow1.WorkflowInterceptor
import com.squareup.workflow1.WorkflowInterceptor.RenderContextInterceptor
import com.squareup.workflow1.action
import com.squareup.workflow1.renderWorkflowIn
import com.squareup.workflow1.runningWorker
import com.squareup.workflow1.stateless
import kotlinx.coroutines.coroutineScope
import kotlinx.coroutines.flow.MutableStateFlow
import kotlinx.coroutines.flow.collect
import kotlin.system.exitProcess

suspend fun main() = coroutineScope {
    val workflow: Workflow<Unit, Unit, String> = Workflow.stateless {
        runningWorker(Worker.timer(1000L)) {
            action("wait-completed") { setOutput(Unit) }
        }

        "Waiting for input..."
    }

    val interceptor = object : WorkflowInterceptor {
        override fun <P, S, O, R> onRender(
            renderProps: P,
            renderState: S,
            context: BaseRenderContext<P, S, O>,
            proceed: (P, S, RenderContextInterceptor<P, S, O>?) -> R,
            session: WorkflowInterceptor.WorkflowSession
        ): R {
            println("onRender: $renderState")

            val contextInterceptor = object : RenderContextInterceptor<P, S, O> {
                override fun onActionSent(
                    action: WorkflowAction<P, S, O>,
                    proceed: (WorkflowAction<P, S, O>) -> Unit
                ) {
                    println("onActionSent: ${action.debuggingName}")
                    proceed(action)
                }
            }

            return proceed(renderProps, renderState, contextInterceptor)
        }
    }

    renderWorkflowIn(
        workflow = workflow,
        scope = this@coroutineScope,
        interceptors = listOf(interceptor),
        props = MutableStateFlow(Unit),
        onOutput = { exitProcess(0) },
    ).collect()
}

That seems to produce the following output:

onRender: kotlin.Unit
onRender: 0
onActionSent: EmitWorkerOutputAction(worker=TimerWorker(delayMs=1000, key=), key=)
onRender: kotlin.Unit
onRender: 0

I was hoping that the "wait-completed" string would be present in that output body but it seems like it's possibly dropped somewhere in the Worker → WorkerWorkflow translation and being replaced with something else. I realize I can still use this string as the Worker's key and have it show up there as a workaround, but still feels odd considering I'm required to provide a name here (even though it's unused).
