Sharing through FRP renders generator useless

[libokj]

Describe the bug

Generator functions (sync or async) with while or for loop (which work smoothly as expected when accessing the app locally) only update the component with the last yield (breaking out of the loop) when accessing the app through FRP. Currently I'm not sure if this is a problem of gradio or the gradio fork of FRP, so I'll open a ticket here for now.

Reproduction

import gradio as gr
import asyncio

# Async version
async def async_query_job_status(job_id):
    for i in range(10):
        yield {
            status: gr.update(value=f"Async: Checking job {job_id}... Step {i+1}/10"),
        }
        await asyncio.sleep(3)  # Simulate async delay

# Sync version
def sync_query_job_status(job_id):
    import time
    for i in range(10):
        yield {
            status: gr.update(value=f"Sync: Checking job {job_id}... Step {i+1}/10"),
        }
        time.sleep(3)  # Simulate blocking delay

with gr.Blocks() as demo:
    with gr.Row():
        start_btn = gr.Button("Start Job")
    job_id_input = gr.Textbox(label="Job ID")
    status = gr.Markdown("Status will appear here")

    start_btn.click(
        async_query_job_status,  # sync_query_job_status,
        inputs=job_id_input,
        outputs=status,
    )

demo.launch(
    share=True,
    # share_server_address="my-frp-server.com:7000",
    # share_server_protocol="https",
)
