We believe that this is now fixed (due to fixes in Parsoid). Please re-open
if it recurs.
How do you know what version of VisualEditor or Parsoid is running? Looking at Erik's comment (bug 50120 comment 6), I try to go to [[Special:Version]] to figure out what exact versions of Parsoid and VisualEditor are running (for debugging purposes and to figure out if this problem is still present in the latest bleeding edge code) and I find that Parsoid and VisualEditor are both marked as version 0.1.0. Not quite helpful for debugging. Splitting this issue out.
