Css Media Query Issue

Hello @artf There is an issue on demo page as well as library in media query. Issue is that if user update style on mobile view first and then the tab view then media query do not work for mobile view. If we update style for desktop first, tab second and mobile third then everything works fine but if we reverse the step mobile view first, tab view second and desktop view third then css/media query will not work for tab and desktop view.

@media (max-width: 480px) {
    #if70u {
        font-size: 20px;
    }
}

@media (max-width: 992px) {
    #if70u {
        font-size: 40px;
    }
}

I think it was due to 480 should be down and 992 should be above. Any help would be appreciated, thanks!
