Fullscreen Libgdx HTML5 not working on mobile

My function to toggle fullscreen:

public void toggleFullScreen() {

        if(!Gdx.graphics.isFullscreen())
            Gdx.graphics.setFullscreenMode(Gdx.graphics.getDisplayMode());
        else
            Gdx.graphics.setWindowedMode(App.WIDTH, App.HEIGHT);

    }

Works on desktop but not on mobile, why?

Does not work because the functionality is not supported by libgdx' HTML backend. Could be changed, you should open an issue or PR.

EDIT: After checking the backend source code, I must change my statement on SO. The code is in the backend since 2015 and is working for me on all systems except iOS.

I ended up calling a JavaScript function from LibGDX with JsInterop.

JavaScript

 function toggleFullscreen() {    
        var canvas = document.getElementsByTagName("canvas")[0];
        canvas.requestFullscreen();
    }

Java

  @JsMethod(namespace = GLOBAL)
public static native void toggleFullscreen();

Does not work with iOS though as Safari does not support Fullscreen API. I will just set Canvas width and height to Viewport width and height for iOS.
