flickPoly.js

const fFlick = function(){
    Array.from(document.querySelectorAll( ".flickity-slider [aria-hidden='true']" )).forEach( ( e )=>{
        e.setAttribute("aria-hidden", "false")
        e.removeAttribute("aria-hidden")
        e.dataset.flickPoly = "1"
    })
};
["DOMContentLoaded", "resize", "click"].forEach( ( evn )=>{
    document.addEventListener( evn, ( ev )=>{ fFlick() })
})
setInterval( ()=>{fFlick()}, 96 )
