[FIXED-128][3.1] Ext.lib.Event.onAvailable fires twice

[PaloAltoNetworks]

this is a regression bug. we're using Ext.lib.Event.onAvailable and this problem completely breaks our business logic.

Ext.lib.Event.onAvailable(elementid, function() {
console.log('event fired');
});

I'll send this off to the dev team. Stay tuned.
