FWIW, I tested this quickly by going to
en.m.wikipedia.org on my browser (which has Adblock Plus 1.8.8) and clicking the left nav, which I know has EventLogging attached to it on mobile web. I saw event.gif in the console, transmitting the following JSON:
{"event":{"name":"hamburger-settings","destination":"/w/index.php?title=Special:MobileOptions&returnto=Main+Page","mobileMode":"stable","username":"Deskana (WMF)","userEditCount":223},"clientValidated":true,"revision":5929948,"schema":"MobileWebClickTracking","webHost":"
en.m.wikipedia.org","wiki":"enwiki"};:
As far as I know, I use default Adblock settings.
If you want to do some troubleshooting with my browser as a control, I am in the office chilling on the hammock, in spite of the rain [1].
Thanks,
Dan
[1]: Yes, that's what it is. Rain. You Californians might call it stormageddon or whatever, but the rest of the world calls it rain. ;-)
