Post shows edit button but trying to save the message gives "post is too old" error
I wrote two posts in the thread https://forum.nim-lang.org/t/8927 and want to edit the second post, https://forum.nim-lang.org/t/8927#58310 . When I edit the post and try to save it I get the error message "This post is too old and can no longer be edited".

I got this message already after a few minutes after posting, and I get it now. But even if the post _was_ too old it wouldn't make sense to show the Edit icon below the post (even when I reload the thread page now). Since posts used to be editable rather for days, I guess the ability to edit is the actually wanted behavior, but it's prevented by the error message instead of a successful submission of the edited post.

My web browser is Firefox 97.0 on Linux.
