The parent task T156351: Add wiki-specific CSS styles for Parsoid Cite output so that it renders exactly like core Cite output describes the problem. We need to add these wiki-specific styles for every wiki that has its own wiki-specific styling. The parent task provides a link that already has these wiki-specific styles for a number of wikis, but doesn't cover all. In some (rare) cases, it might be simpler to tweak the current wiki styles to avoid having to add more complexity to the markup and CSS to replicate existing styles.
There is no hard deadline, but ideally by end of 2017, we will have the parent tasks resolved and citations in VE look identical to citations in the read view.
