I use the source editor, and often put references between <references>...</references> to keep he source uncluttered.
It seems that the visual editor will insert unnecessary quotes around the names of ALL such references, whenever it is used to edit the article. See for example [https://en.wikipedia.org/w/index.php?title=Graphene&type=revision&diff=970831602&oldid=970749638 This change] (search for <references>)
As that example shows, that insertion of unnecessary quotes confuses the "diff" algorithm and creates huge and confusing change logs. Could you please fix the visual editor so that it preserves any entries between <references> and </references> unchanged?
