Differences in functionality in Web browsers and QML for the JavaScript String localeCompare API

let strings = ["华数酷喵   ","芒果TV车载版   ", "哔哩哔哩   ", "车鱼视听   ", "爱奇艺   ", "唱吧   ", "USB", "C", "B", "A"];

strings.sort(function(a, b)

{ var titleA = a   var titleB = b   return titleA.localeCompare(titleB, "zh-CN"); }

);

console.log(strings)

expected output and web browser output
["爱奇艺", "哔哩哔哩", "唱吧", "车鱼视听", "华数酷喵", "芒果TV车载版", "A", "B", "C", "USB"]

qml output
[A,B,C,USB,芒果TV车载版,爱奇艺,车鱼视听,唱吧,哔哩哔哩,华数酷喵]
