I had a tab open on https://ell.stackexchange.com/questions, while I was writing a question on another tab. (I didn't notice I had two tabs open on the same site; probably a tab was open to a different Stack Exchange site, I was notified of a new comment/answer, and I clicked on the notification to read the full comment/answer.)
When I wrote the question, I checked the other tab to see if new questions were asked, and I found a box telling me that a new question was asked. When I clicked on that box, a new question was shown in the page, but I noticed that the question (mine) was reported to be modified, while I created it. My previous question was reported as asked.
In which cases the questions on https://ell.stackexchange.com/questions are shown as modified, instead of asked? I thought the questions on that page should always show asked. This is the first time I saw modified on the question page. Even on other Stack Exchange sites, I have never read modified.
