SLIDER problem only on mobile

I also did a test with Enfold 4.4.1 … With that version everything is ok. The problematic version is 4.5.2 but also updating to 4.5.7 the problem is not solved.

I ran a test using safari user agent to simulate the view on iphone …
I think there is an error on the
wp-mediaelement.min.js

!function(a, b) {
function c() {
function a() {
“undefined” != typeof _wpmejsSettings && (c = b.extend(!0, {}, _wpmejsSettings)), c.classPrefix = “mejs-“, c.success = c.success || function(a) {
var b, c;
a.rendererName&&-1 !== a.rendererName.indexOf(“flash”) && (b = a.attributes.autoplay && “false” !== a.attributes.autoplay, c = a.attributes.loop && “false” !== a.attributes.loop, b && a.addEventListener(“canplay”, function() {
a.play()
}, !1), c && a.addEventListener(“ended”, function() {
a.play()
}, !1))
}, c.customError = function(a, b) {
if ( – 1 !== a.rendererName.indexOf(“flash”)||-1 !== a.rendererName.indexOf(“flv”))
return ‘‘ + mejsL10n.strings[“mejs.download-video”] + “”
}, b(“.wp-audio-shortcode, .wp-video-shortcode”).not(“.mejs-container”).filter(function() {
return !b(this).parent().hasClass(“mejs-mediaelement”)
}).mediaelementplayer(c)
}
var c = {};
return {
initialize: a
}
}
a.wp = a.wp || {}, a.wp.mediaelement = new c, b(a.wp.mediaelement.initialize)
}(window, jQuery);
