I had submitted a comment on a ticket, which went through find, but then wanted to assign it to myself. So I hit the 'take' button and nothing happened.

Turns out pagure.io had started refusing connections. But there's no indication that an asynchronous request was running, and no indication that it had failed.

I haven't looked at how the underlying code works, but I guess it should relatively be simple to:

• unhide a spinner that lives next to the 'Take' botton, and
• handle the rejection of the promise and fill in/unhide some div that's probably already there for flashing errors
