I stumbled over this in the reopen queue on https://stackoverflow.com/review/reopen/33390644.
My intent was to choose "Leave Closed", but IMO, the close reason should be "Not a question on programming" (because the question is about using the shell history interactively).
I therefore clicked on "Leave Closed", and on "Submit". In the opening dialogue I clicked on the circle in front of "This question doesn't meet the ... guidelines". A new dialogue window opened, from which I clicked on the topmost circle, i.e. in front of "Not about programming". The circle got selected, but when I now click on the "Keep Closed" button on bottom, I get the error message "You must select a reason...", although the reason is clearly shown as selected.
I'm using Firefox 107.0.1 on Windows 10.
