Fullscreen exiting immediately

[reinildo]

Hi. Thanks for the great work.
I've forked a codepen from Samme, it is an example to go full screen with phaser.
If you apdate phaser version to 3.16.2 it stops working. Up to 3.16.1 it works fine.
here are the links to test:

Thanks

3.16 contains built-in support for fullscreen, and this direct approach is conflicting with it. If you wish to carry on doing it your way, rather than using the Scale Manager, that is fine, but you need to stop the Scale Manager from handling the change request. The easiest way to do this is to replace the ScaleManager.onFullScreenChange function (just set it to a blank function).

Alternatively, if you don't need the Scale Manager at all, you can just call this.scale.stopListeners() to unbind it from the fullscreen handlers.
