Json Type value can not show in Example component

[hiwei93]

Describe the bug

The app contains a gr.JSON component, for which I intend to provide examples using gr.Examples. However, gr.Examples fails to display the JSON value.

No errors are raised, but the component simply does not show any content.

Reproduction

import gradio as gr

def get_examples():
    return [
        ["aabc", None, '{"a": 1, "b": 2}'],  # this will not display
        ["2134", None, {"c": 3, "d": 4}],  # this will not display
        ["abfgj", None, None], # this will not display too
     ]


with gr.Blocks() as demo:
    text = gr.Textbox()
    video = gr.Video()
    vinfo = gr.JSON('{"a": 1, "b": 2}')
    gr.Examples(
        get_examples(),
        inputs=[text, video, vinfo],
    )
demo().launch(
        debug=True,
)
