Emitewiki2 Thread:1773148 I would not expect this handler to actually fire when the Event occurs, because I have not added an mw.hook.fire line   wikipage.content fired by the mediawiki platform and some 3rd-party scripts, when needed. so, yes, when you adding listener to the wikipage.content event, you will recieve some events from other scripts.

if you want to use your own hook, than pick another name. in general case, i would suggest to not fire wikipage.content event: you don't know what it does, so you can break some things. listen it, if you need it, but don't fire unless you will learn what it does, when it does, and why it supposed to be fired.
