How do re-open votes expire?
I couldn't find anything in the help center, but I did find https://meta.stackexchange.com/a/123786/38765
I voted to re-open How to follow only specific issues on Github, instead of watching an entire project? on June 30, and my re-open vote has expired.
It's possible, but seems unlikely, that the question has been viewed 100 times since I voted to re-open (it's currently at 230 views).
Does a re-open vote expire when a question has been viewed 100 times since the vote has been cast, and a day has passed, or is a day passing sufficient when the question has been viewed 100 times, ever, even if those views were before the re-open vote was cast?
