Hi!
I suspect this might be related to the input/autofill browser plugin you might be using, at least I can see spin icon on your screenshot, here: https://i.imgur.com/hoV4k3U.png
I tried to replicate the issue on multiple browsers and test environments, but it works, and there are no other reports of it either. Can you please try de-activating that input/autofill browser plugin, and try it again? Some of these plugins block input/keyup/keydown etc.. events, which may explain the issue.
I hope this helps!
