This question already has an answer here:  I encountered a bug
regarding the Next button in the review section.  Steps to
reproduce:    • Review a "first post".   • Complete the first
review regularly and review another "first post".   • Start
editing the post.   • Wait for some time, so that someone else
likely completes the review.   • Click the browser's back
button.   • Try clicking the Next-button.  Expected behavior:
The next review is being displayed, or a message appears stating
that there are no posts to review.  Current behavior:  Nothing
happens. The button looks "clickable", but cannot be clicked.
After reloading the page the button gets clickable.  Edit: After
several "edit" -> "cancel" -> "edit" -> "back" cycles I managed
to get this result (Note the two "cancel"-links at the top):

editing the post, and then Click the browser's back button. Why
would you cilck the back button, why not click "Cancel"? –  LBT
