Simon MacDonald commented on CB-829:
------------------------------------
Sweet, tested on Android where I added the same event listener twice and added
two different event listeners and everything works great.
> Calling document.addEventListener("backbutton") with the same callback
> function more than once results in never being able to fully remove the
> listener

> I ran into this problem while running mobile spec tests on Android. If I
> click the Events->Intercept Backbutton link twice then clicking the HW back
> button results in two console logs saying the back button was intercepted.
> This is okay. Clicking Events->Stop intercept of back button then clicking
> the HW back button results in one console log saying the back button was
> intercepted. This is still good.

> This is where things break down. I can click the remove event listener button
> as many times as I want but it will never be removed.
