That "pawn" bug (bugzilla:48346) must be one of the weirdest bugs I've ever seen. Here's another strange one, seen in Firefox 20.0.1:
- Go to w:Mersin İdmanyurdu SK and invoke VisualEditor
- The cursor should automatically be on the first (blank) line. Start typing
- As well as a appearance of a pawn, strange duplication of characters starts to occur
Not only is VE playing chess, but perhaps also some drinking games :)
