Javascript 如何让js.map文件与UMD模块一起工作？

我有以下TS文件：

地图测试 MapModuleTest.ts 当我尝试在Chrome或FireFox中设置断点并调试

MapTest

的TypeScript时，一切正常。当我尝试调试

MapModuelTest.ts

时，在Chrome和Firefox中，TypeScript行似乎比实际的JS提前了两行。因此，如果我在这一行设置一个断点，

const six=4+2它的行为就好像JS实际上在这一行中断一样
consttwo=zero+2（即
0
定义为
0
，但
2
是
未定义的
）

这是已知的bug吗？UMD生成是否需要一些不同的东西才能正确地为.map文件工作

调试器窗口更有趣的是，本地调试器与控制台不匹配。

下面是相关的JS和Map文件

MapTest.js
MapTest.js.map
MapModuleTest.js
MapModuleTest.js.map
我已将此记录为错误。希望这可以得到修复：


更新
这似乎是我用于pollyfill promises的es6 promise库的一个问题。一旦我切换到某物>=es6进行编译，映射就正常工作了

module Test
{
    export function myTest() {
        const zero = 0;
        const two = zero + 2;
        const four = two + two;
        const six = four + two;
        console.log(six);
    }
}

export module Test
{
    export function myTest() {
        const zero = 0;
        const two = zero + 2;
        const four = two + two;
        const six = four + two;
        console.log(six);
    }
}

var Test;
(function (Test) {
    function myTest() {
        var zero = 0;
        var two = zero + 2;
        var four = two + two;
        var six = four + two;
        console.log(six);
    }
    Test.myTest = myTest;
})(Test || (Test = {}));
