devServe hot reload not available?

Hi I'm learning Electron and looking into Fiddle's source.

I noticed that `electron-forge/plugin-webpack` is used and the config shows:

```
devServer: {
// Disallow browser from opening/reloading with HMR in development mode.
open: false,
liveReload: false,
hot: 'only',
},
```

I tried turning `liveReload` on but not getting anything meaningful.

So looks like somehow hotloading, etc, are disabled . Would love to know why that is the case. Thanks!
