[BUG] dcc.Patch() wipes persistence of sibling pattern-matching elements

Comienza ejecutando la aplicación mínima de Dash del issue con Dash 4.4.0; después, sigue cómo dcc.Patch() actualiza children con pattern-matching IDs y cómo se restaura persistence. Se considera terminado cuando añadir un nuevo hermano conserva la persistence local de los inputs existentes con pattern matching, mientras que la persistence no relacionada permanece sin cambios.

Environment

dash                 4.4.0

When patching a new element to list of elements with pattern matched ids, persistence is wiped from all sibling IDs.

Minimal example:

from dash import ALL, Dash, Input, Output, Patch, dcc, html, clientside_callback, callback

app = Dash(__name__)

def make_input(index):
    return dcc.Input(
        id={"type": "inp", "index": index},
        value="initial",
        persistence=True,
        persistence_type="local",
    )


app.layout = html.Div(
    [
        html.Button("add", id="add"),
        html.Button("clear", id="clear"),
        html.Div([make_input(0), make_input(1)], id="container"),
        html.Div(id="display"),
        html.Pre(id="storage"),
        dcc.Interval(id="local_storage_poll", interval=250),
        dcc.Input("Hello, I don't wipe", id='non-pattern-matching-id', persistence=True, persistence_type='local')
    ]
)


@callback(
    Output("container", "children"),
    Input("add", "n_clicks"),
    prevent_initial_call=True,
)
def add_input(n):
    patch = Patch()
    patch.append(make_input(n + 1))
    return patch


@callback(Output("display", "children"), Input({"type": "inp", "index": ALL}, "value"))
def show(values):
    return "|".join(values)


# Debug info, show local storage to make it easier to noticed when it's wiped
clientside_callback(
    """
    function display_persisted_vals() {
        return Object.keys(window.localStorage)
            .filter(k => k.startsWith('_dash_persistence.'))
            .map(k => k + ' = ' + window.localStorage.getItem(k))
            .join('\\n') || '(nothing persisted)';
    }
    """,
    Output("storage", "children"),
    Input("local_storage_poll", "n_intervals"),
)

# Debug helper, clear local storage to do a clean test
# (helpful after the fix when the storage doesn't wipe constantly, lol)
clientside_callback(
    """
    function clear_persistence() {
        Object.keys(window.localStorage)
            .filter(k => k.startsWith('_dash_persistence.'))
            .forEach(k => window.localStorage.removeItem(k));
        window.location.reload();
        return window.dash_clientside.no_update;
    }
    """,
    Output("clear", "n_clicks"),
    Input("clear", "n_clicks"),
    prevent_initial_call=True,
)


if __name__ == "__main__":
    app.run(debug=True)

Here is a run of the minimal example app

Persistence works without a patch.
When a patch is applied persistence is wiped from siblings, but not from unrelated elements.
