angular - 使用 ie11 打开时出现 SCRIPT1002 错误

Question

在我将 ngx-perfect-scrollbar 从 V7.2 升级到 V10.1.1
角度版本：angular/compiler-cli@7.2.15
节点版本：v14.17.0
ngx-perfect-scrollbar：10.1.1
tsconfig.json：

{
    "compileOnSave": false,
    "compilerOptions": {
        "baseUrl": "./",
        "outDir": "./dist/out-tsc",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es5",
        "typeRoots": [
            "node_modules/@types"
        ],
        "lib": [
            "ES2018",
            "es5",
            "ScriptHost",
            "dom"
        ],
        "paths": {
            "ngx-perfect-scrollbar": [
                "lib"
            ]
        }
    }
}

索引页中的错误行：

const PERFECT_SCROLLBAR_CONFIG = new _angular_core__WEBPACK_IMPORTED_MODULE_2__["InjectionToken"]('PERFECT_SCROLLBAR_CONFIG');
class Geometry {
    constructor(x, y, w, h) {
        this.x = x;
        this.y = y;
        this.w = w;
        this.h = h;
    }
}
class Position {
    constructor(x, y) {
        this.x = x;
        this.y = y;
    }
}

为什么我已经将目标设置为“es5”，但是当使用 ie11 打开时我看到了“class Geometry..”
