4.28.0 and later -- breaking change so components being updated in queued function calls are not interactable

[howardwu1]

Describe the bug

When I use a queued function which updates one or more components, those components are no longer interactable (example highlighting text in a label or interacting with a plotly chart). In 4.27, this was still functional and I tried searching through the 4.28 changelog to figure out why but haven't found anything.

Reproduction

import gradio as gr


with gr.Blocks(theme=gr.themes.Soft()) as demo:
 
    title = gr.Label( "hello" )

    changeTitleBtn = gr.Button("Change Title")

    changeTitleBtnEvent= changeTitleBtn.click(
        fn=lambda: {
                title: "goodbye",
        inputs=[
        ],
        outputs=[
            title,
        ],
        every=0.5,
    )

if __name__ == "__main__":
    demo.queue(max_size=20)
    demo.launch()

Severity

I can work around it

[sbarman-mi9]

Well, regression again. This is important when users want to interact with elements inside chat interface while the function is queued and streaming.
