Media query difference from Admin menu and Top menu

Hi all,
It seems that the media query of admin menu have 768px as breakpoint size,

@media screen and (max-width: 782px)
html #wpadminbar {
    height: 46px;
    min-width: 240px;
}

but top menu change at 720px

@media only screen and (max-width: 719px)
.header-mobile-sticky .mobile-sticky {
    position: fixed;
    width: 100%;
}

Does It a theme issue or WP one??
It’s also seems that there are some problem with mobile vision at that resolution, but I hope It’s a conseguence.

Thank Renzo
