In WP 5.6, jQuery UI was updated to 1.12.1, dropping support for the
zIndex()
function. See #499 for more information.While the recommended approach is to replace this function using stacking elements, the affected code in this plugin can just as easily be replaced with the
.css('zIndex')
function since the originalzIndex()
function was just an abstraction method for the same. This is documented here: https://api.jqueryui.com/1.12/zIndex/
