Image Compare Block provided by jetpack does not work.

Image Compare Block (*) provided by Jetpack does not work when using a3 Lazy Load.

I first checked the output source code and said “Exclude Images”
I thought about setting the class to.

However, the corresponding block was not given a class as shown below.

<div class = "jx-image jx-left" style = "width: 50%;"> <img src = "image_url_example.png" alt = ""> </ div>
<div class = "jx-image jx-right" style = "width: 50%;"> <img src = "image_url_example.png" alt = ""> </ div>

I also tried writing something like “.jx-image img” to “Exclude Images”, but this didn’t work.

Is there any solution?

Thank you
