search box css (width:min-content;) not working on search box

It appears some of my search box widget css is no longer working after upgrading to 5.2, specifically line-height and width:min-content; (which is supposed to constrain to the width of the placeholder.)

#search-2 .search-form input[type=”search”] { //#search-2 is widget id for widget shortcode plugin
overflow: auto;
width: min-content;
}
