I have been getting this issue since this morning, I think this has something to do with changing image size when the size of an image gets adjusted or changed. I do not have the exact steps to reproduce for now.But it happened this one time when I changed the thumbnail left aligned image to centre float. This is the page where you will see the image on which I made the change and getting the edit conflict error : http://en.wikipedia.beta.wmflabs.org/wiki/9thjunechrome?veaction=edit We had encountered similar kind of issue quiet a while ago, which was fixed: https://bugzilla.wikimedia.org/show_bug.cgi?id=62172 I am not sure, if the same cause is behind the bug or not
There is a very weird issue, probably introduced by Ed's extension nodes rewrite. Any extension node's children get duplicated on the way back to Parsoid: a hieroglyphs <table> gets two <tbody>s, a gallery <ul> contains all of its <li>s twice, etc.
