if you run into error `Failed to construct 'HTMLElement': Please use the 'new' operator, this DOM object constructor cannot be called as a function.
e.g. https://github.com/microsoft/vscode-webview-ui-toolkit you may need to setup `@babel/plugin-transform-classes` as below shown.

```ts
// Failed to construct 'HTMLElement': Please use the 'new' operator, this DOM object constructor cannot be called as a function.
[babelPluginTransformClass, { loose: false }];
```

```ts

babelOptions: {
    plugins: [
    [
        env.resolve(import.meta.url, '@babel/plugin-transform-classes'),
        {
        loose: false,
        },
    ],
    ],
},
```
