gr.Plot not firing .change event

[Josef-Haupt]

Describe the bug

As I understand the description of the .change event in the docs, if the plot changes from user input or function update, the event should fire, but it currently does not, see my example.

Expected behaviour would, be that the change event fires on blocks.load and lat.change/lon.change as well.

Reproduction

import gradio as gr

import plotly.express as px


def plot_map_scatter_mapbox(lat, lon):
    fig = px.scatter_mapbox(
        lat=[lat],
        lon=[lon],
        zoom=3,
        mapbox_style="open-street-map",
    )
    fig.update_layout(margin={"r": 0, "t": 0, "l": 0, "b": 0})
    return fig


def print_lat_lon(lat, lon):
    print(lat, lon)


with gr.Blocks() as blocks:
    map_plot = gr.Plot()

    lat_number = gr.Slider(
        minimum=-90,
        maximum=90,
        value=0,
        step=1,
        label="Latitude",
    )
    lon_number = gr.Slider(
        minimum=-180,
        maximum=180,
        value=0,
        step=1,
        label="Longitude",
    )

    blocks.load(plot_map_scatter_mapbox, inputs=[lat_number, lon_number], outputs=map_plot)
    lat_number.change(plot_map_scatter_mapbox, inputs=[lat_number, lon_number], outputs=map_plot, show_progress=False)
    lon_number.change(plot_map_scatter_mapbox, inputs=[lat_number, lon_number], outputs=map_plot, show_progress=False)
    map_plot.change(print_lat_lon, inputs=[lat_number, lon_number], show_progress=False)


blocks.launch()
