So with our latest changes we've also deferred the rendering of shields until the are first focused (tapped, in mobile). This should completely eliminate any page load bottleneck these were causing.
The % of time spent in these functions has been reduced somewhat
according to my latest profiling, but the MobileFrontend nth-child
selector /still/ exists so it's still ridiculously high on mobile.
I'm not quite sure at which point we say that we have succeeded in
improving VE mobile performance but when someone finally bothers
reviewing https://gerrit.wikimedia.org/r/131892 we should have a
better idea if mobile is on par with desktop.
