Question: Reset ErrorBoundary outside handle_error

[canyon-service]

In the second example "Resetting the error boundary"
Why does handle_error closure not allow any mutation as I would like the reset (errors: ErrorContext [errors.clear_errors()]) to be handled outside the ErrorBoundary.

fn App() -> Element {
    let mut multiplier = use_signal(|| String::new());
    let mut rst: Signal<Option<ErrorContext>> = use_signal(|| None);
    rsx! {
        input {
            r#type: "text",
            value: multiplier,
            oninput: move |e| multiplier.set(e.value())
        }
        ErrorBoundary {
            handle_error: |errors: ErrorContext| {
                multiplier.set("mutate".to_string()); // Not allowed
                rst.set(Some(errors.clone())); // Not allowed, to be reset by external
                rsx! {
                    div {
                        "Oops, we encountered an error. Please report {errors:?} to the developer of this application"
                    }
                }
            },
            Counter {
                multiplier
            }
        }
    }
}
