You are only seeing the back arrow since there is only backwards history for that tab. If you go back by clicking the back button, you will see both arrows appear. Does that explain the behavior you are seeing? Thanks for checking on how to write a good bug. (Saw that in your tabs) We really appreciate you taking the effort to file a good bug.
