Change note for transforming NodeLists to Arrays

Found that the issue is not needing to use a `for ... of` loop, but to add in `@babel/plugin-transform-spread` (whose default option is `loose:false`, which will override a global `loose:true` on `@babel/preset-env`). This transformation works correctly, including when using a `.browserlistrc` that includes `IE 11`. Thanks @calebeby.

 To convert an iterable object (e.g. [NodeList]) to an array, use [array spread syntax][Array Literal Spread Syntax] `...` instead of [Array.from].

+#### Note
+
+If using Babel with `@babel/preset-env` with option `loose:true`, and are transpiling to older targets in a `.browserlistrc`, you may need to add the following to your Babel config (e.g., `babel.config.js`):
+
+```js
+plugins: [
+  ...,
+  '@babel/plugin-transform-spread',
+  ...
+]
+```

+(The default option for this plugin is `loose:false`, which will override the global setting)
