Right now this is loaded in AddLinkArticleTarget.prototype.beforeLoadSuccess, which means we only begin loading the addlink data after the VE modules and the Parsoid HTML have already been loaded. We should instead load this in parallel.
This will require some init code in ext.growthExperiments.SuggestedEdits.Guidance.js or similar that is able to fire the request for the addlink data before the AddLink module has loaded, perhaps in the same ve.loadModules hook listener that is used to load the AddLink module. AddLinkArticleTarget then needs to get a hold of this data promise and wait for it before allowing loadSuccess to happen.
