* Electron version: 1.4.6
* Operating system: Windows 10

### Expected behavior

After minimizing the window it should restore to the same size.

### Actual behavior

After minimizing the window it is restored to a larger width.

### How to reproduce

The issue started with Electron 1.4.5 and will only appear when you use `minWidth` property in browser window config. As an example:

```javascript
const windowConfig = {
	title: "Test app",
	width: 800,
	height: 600,
	minWidth: 800
};

const mainWindow = new BrowserWindow(windowConfig);
```

  } else {
