Steps to reproduce:
1.Open a page with VE that has some references and a reference list
2.Try to open the reference list by clicking on it
Observed Result:
The dialog does not open , but a broken UI, following error in the console:
TypeError: this.node.getAttribute(...).body is undefined
Uncaught TypeError: Cannot read property 'extsrc' of undefined
This is caused by a bug in Parsoid. The page in question ( http://en.wikipedia.beta.wmflabs.org/wiki/Newpageachrortest?veaction=edit ) contains references in two groups, so two reference lists are added automatically. However, these two reference lists have the same about attribute (which is wrong) and are adjacent, so VE follows the about grouping protocol and groups them together as one node.
