I just experienced the exact symptoms described in [this previously fixed bug](http://meta.stackexchange.com/questions/184642/why-does-the-questions-closed-status-disappear-when-clicking-to-load-a-new-edit) on a [brand new question on Stack Overflow](http://stackoverflow.com/questions/28281082/what-is-differ-between-isset-empty).  

Note that while the symptoms were the same (the dupe notice disappearing), it happened under slightly different circumstances, in that it was a live, active question with other people editing their own answers, rather than opening a new tab to an old, already closed question.

Reconfirmed the bug on [this question](https://stackoverflow.com/questions/28329498/strange-behavior-using-is-operator-with-strings).  The answer got edited, reloading it caused the notice to disappear.  I used [this search](https://stackoverflow.com/search?tab=newest&q=answers%3a1%20closed%3ayes) to watch for likely instances of it occurring.  Note at the time of writing, that question has 2 reopen votes, but it is/was a duplicate at the time of refreshing the answer.


**Update**

Seems that it's not just happening on duplicates.  I've just witnessed the same behaviour on a question with a Bounty notification banner - reloading a edited answer also causes the bounty notification to disappear.
