Cannot display outputs when reusing cached examples

[aaronng91]

Describe the bug

When using Examples and setting cache_examples=True, the inputs/outputs load fine when you start app for the first time. However, if you reload the app which reads from the same cache, the outputs no longer load. No examples or methods have changed.

Reproduction

import gradio as gr

def combine(a, b):
    return a + " " + b

with gr.Blocks() as demo:
    txt = gr.Textbox(label="Input", lines=2)
    txt_2 = gr.Textbox(label="Input 2")
    txt_3 = gr.Textbox(value="", label="Output")
    btn = gr.Button(value="Submit")
    btn.click(combine, inputs=[txt, txt_2], outputs=[txt_3])
    
    gr.Markdown("## Text Examples")
    gr.Examples(
        [["hi", "Adam"], ["hello", "Eve"]],
        [txt, txt_2],
        txt_3,
        combine,
        cache_examples=True,
    )

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

Screenshot

Output loads fine when initializing cache for the first time
