Describe the issue in a sentence or two.

After adding alt text to an image and adding the lazyload plugin, an image flickering is happening very briefly, as it show the alt text before the image. You can see it here if you refresh the demo a few times: https://codesandbox.io/p/sandbox/lazy-loading-lqip-react-js-sdk-2-0-forked-c3hsk6?file=%2Fsrc%2FLazyloading.js%3A34%2C40

I've tried adding a placeholder too and the issue remains the same. using onError to add a default image as shown here doesn't seem to work as well.

Hi @victorcarvalhosp. Thanks for flagging this with us. I have raised this internally (ref SNI-8022) and we will provide you with updates when we can.

Hi @dannyv-cloudinary! Thanks for looking into it. Do you guys have some updates on this? Our site heavily relies on images, and we need lazy load to work properly on it.

Maybe you have some workaround that we cab do in the meantime?

Hi there @victorcarvalhosp. Currently, there is a fix being worked on, and although I don't have a specific ETA I do hope it will be merged soon. I tried tying this ticket to your account but couldn't find your cloud "dessmo". Can you please your cloud name?
