Steps to replicate the issue (include links if applicable):

• Visit the page Algol on en-wiki without Parsoid enabled. The topbar includes sky coordinates for finding the constellation: (arrow added by me)
  
• Enable Parsoid
• The coordinates are completely broken:
  

What happens?:
Instead of correctly displaying the sky coordinates, we get broken parsing. The full link that is returned is:
