Found an interesting bug just now, more details in the answer - "?"
This is about that "You haven't posted your answer yet. You'll lose your progress if you navigate away" warning message.
As I'm sure most of the contributors know, if you're writing an answer and you happen to accidentally hit the Close tab or Close page buttons of your browser, you get a warning message that goes like this
"You haven't posted your answer yet. You'll lose your progress if you navigate away"
As a side note, this an extremely useful safeguard - it spared me the trouble of having to rewrite my answer a couple of times :)
However, I just noticed that, at least in one case, you can close a tab or page without getting this message.
I wanted to write an alternative answer to a question that already had an answer posted, but I changed my mind in the process. When I closed my tab, it closed without this reminder.
I tested this on several other answers, and the results were the same
