Lines 747 to 753 in c2e3571

	// TODO: do not update menu immediately!
	// Instead, only set a flag that the menu must be updated. Then,
	// wait for calls that edit the same message, and inject the
	// payload there. This will both prevent flickering and save an
	// API call. If no such call is performed, fall back to
	// performing an extra API call.

We want to perform menu updates lazily. This prevents both flickering and is more efficient.

Can be disabled by passing { immediate: true } to ctx.menu.update.
