Photino: the confirmation modal in MuteButton doesn't appear the first time

[lapulpeta]

confirmationModalRenderFragment = new RenderFragment(builder =>
{
    builder.OpenElement(0, "div");
    builder.AddEventStopPropagationAttribute(1, "onclick", true);
    builder.OpenComponent<ConfirmationModal>(2);
    builder.AddComponentReferenceCapture(3, instance => { confirmationModal = instance as ConfirmationModal; });
    builder.CloseComponent();
    builder.CloseElement();
});
await InvokeAsync(() => ShowConfirmation());

Apparently when ShowConfirmation is called confirmationModal is still null so nothing happens.
