StatusBar.show() doesn't work on Windows Phone 8.1

The status bar is not displayed in Windows Phone 8.1 (emulator).

Reproduce as follows:

1. Run the commands:
cordova create test
cd test
cordova platform add windows
cordova plugin add cordova-plugin-statusbar

2. Edit www\js\index.js, add the lines below just after "app.receivedEvent('deviceready');":

StatusBar.overlaysWebView(false);
StatusBar.styleDefault();
//StatusBar.backgroundColorByHexString("#C0C0C0");
StatusBar.show();

3. Run command:
cordova build windows

4. Using VisualStudio (2015), open the platforms\windows\CordovaApp.sln solution and set "CordovaApp.Phone (Windows Phone 8.1)" as the Startup Project. Windows. Then run using "Emulator 8.1 WVGA".

When the CordovaApp has started and "deviceready" has been fired, the status bar is gone.
