[Question] How to display placeholder when the image is still be fetched while visible in the viewport?

Hi guys, I was using this library to lazy-load my images, I was also using my custom placeholder component.

As I observe, as soon as the images are in the viewport, the placeholder will be immediately replaced with the `img` tag. However, in my case, my image fetching is slow, so the image goes blank for a while until the fetching done and the browser paints it.

So my question is there any way to show the placeholder until the image is completely fetched?

Thank you
