延迟加载无法与Smartphoto灯箱配合使用的图像

Question

延迟加载的图像不适用于我正在使用的Smartphoto灯箱。

这部分触发立即加载图像，而不是在达到阈值时加载图像：

是否有一种方法可以使<a href="https://via.placeholder.com/350x120" class="js-smartPhoto" data-caption="test" data-id="test" data-group="test"><img src="https://via.placeholder.com/10x10" class="svg" /> 内部的图片也可以延迟加载？
