Nice @freddyaboulton taking a look through this now. Is it possible to add a unit test for this btw?

[abidlabs]

Thanks @freddyaboulton it looks like this fixes the original issue, but this does not seem to work for functions that return an updated component. Repro:

So this works:

import gradio as gr

with gr.Blocks() as demo:
    text = gr.Textbox()
    out = gr.Textbox()
    gr.DeepLinkButton()
    text.submit(fn=lambda x: x, inputs=text, outputs=out)
demo.launch()

But this does not:

import gradio as gr

with gr.Blocks() as demo:
    text = gr.Textbox()
    out = gr.Textbox()
    gr.DeepLinkButton()
    text.submit(fn=lambda x: gr.Textbox(x, lines=int(x)), inputs=text, outputs=out)
demo.launch()

Screen.Recording.2025-05-15.at.11.12.35.AM.mov

You'll notice that the output is not restored, neither the value nor the number of lines

Thanks for catching that @abidlabs ! I fixed the issue and added a unit test as well
