Solution 1:

Here is a workaround with ::before element.

HTML:

<div class="img-wrapper">
    <img src="Screenshot_2.png" alt="">
</div>

CSS:

.img-wrapper {
    display: inline-block;
    position: relative;
}
.img-wrapper::before {
    position: absolute;
    background: #000;
    width: 100%;
    height: 100%;
    content: "";
    z-index: 1;
    padding: 20px;
    left: -20px;
    top: -20px;
    border-radius: 50%;
    transition: .5s;
    opacity: 0;
    visibility: hidden;
}
.img-wrapper img {
    z-index: 2;
    position: relative;
    display: block;
}
.img-wrapper:hover::before {
    opacity: 1;
    visibility: visible;
}
