jss-snapshot-serializer: jss nested selector or @media queries are not added to the json snapshot

[Danitoro]

JSS constant:
const style = {
gridItemOne : {
"@media screen and (max-width: 577px)": {
padding: "8%"
},
paddingBottom: "1%",
paddingLeft: "1%",
paddingTop: "2%"
}
link : {
"& a" : {
color: "#007bff"
},
"& a:hover" : {
color: "#0056b3"
}
};

If I change the padding: "8%" or the color of "& a", is not detected by the snapshot test however, if I change paddingBottom: "1%" is detected by the test of the snapshot.

Do you know how to add selectors or @media queries to the snapshot?

Thank you,
Daniel
