MultimodalTextbox interactive=False doesn't work with the submit button

[sthemeow]

Describe the bug

When setting interactive=False with MultimodalTextbox, it doesn't disable the submit button.
The text entry and image upload button are disabled so the content cannot be changed, but the submission can still take place.

import gradio as gr


def greet(a, c):
    return gr.MultimodalTextbox(interactive=False), a, c+1


with gr.Blocks() as demo:
    a = gr.MultimodalTextbox(interactive=True, show_label=False) 
    b = gr.Textbox(interactive=False, show_label=False)
    c = gr.Number(interactive=False, show_label=False) 
    a.submit(fn=greet, inputs=[a, c], outputs=[a, b, c])

if __name__ == "__main__":
    demo.launch()

I can still click the submit button multiple times after it is set to be non-interactive.
