* 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);
```

#if defined(OS_WIN)
  if (IsMinimized())
    return window_->GetRestoredBounds();
#endif
  return window_->GetWindowBoundsInScreen();
}
gfx::Rect NativeWindowViews::GetContentBounds() {
  return web_view_->GetBoundsInScreen();
}
gfx::Size NativeWindowViews::GetContentSize() {
#if defined(OS_WIN)
  if (IsMinimized())
    return NativeWindow::GetContentSize();
#endif
  return web_view_->size();
}
void NativeWindowViews::SetContentSizeConstraints(
    const extensions::SizeConstraints& size_constraints) {
  NativeWindow::SetContentSizeConstraints(size_constraints);
  
  
  if (window_ && window_->widget_delegate())
    window_->OnSizeConstraintsChanged();
#if defined(USE_X11)
  if (resizable_)
    old_size_constraints_ = size_constraints;
#endif
}
