I can not reproduce using your stepts, however, I have witnessed this when doing some template/helpder configuration for a few hours of fiddling around, approximately three times in the hour I had to reload the webpage to be able to use the keyboard again. Unfortunately, I cannot reproduce it, but I can confirm it happens.
