尝试增加event，例如tooltip:show，为什么从不被执行

if (OnLegendClick.HasDelegate)
await JS.InvokeVoidAsync(InteropSetEvent, Ref.Id, "legend-item:click", chartRef, nameof(JsLegendClick));

if (OnElementClick.HasDelegate)
await JS.InvokeVoidAsync(InteropSetEvent, Ref.Id, "element:click", chartRef, nameof(JsOnElementClick));

if (OnTooltipChanged.HasDelegate)
await JS.InvokeVoidAsync(InteropSetEvent, Ref.Id, "tooltip:show", chartRef, nameof(JsOnTooltipChanged));
