Notes

Not supported in some versions of Android's old WebKit-based WebView.

While a window.CustomEvent object exists, it cannot be called as a constructor. Instead of new CustomEvent(...), you must use e = document.createEvent('CustomEvent') and then e.initCustomEvent(...)
There is no window.CustomEvent object, but document.createEvent('CustomEvent') still works.
