Event.APPLICATION_SUSPEND does not work in HTML5 version

E1e5en

I added event handling (Event.APPLICATION_SUSPEND, Event.APPLICATION_RESUME) to the Dashing Ball game to pause the game. This doesn't work for the web version.
Tell me, what's not working for the web version yet? Maybe there is a description of the differences of functions on the platforms.

I saw the solution, how you can pause the game: solution from @SinisterSoft user.
But the question describing the difference in functionality on the platforms is still open and not completely transparent.

Update:
Alternatively, you can try to track Web API events in a similar way:
- visibilityEvent
- focusin_event
- focusout_event
