In this example, we can input some info into username and password form input. When it focus on password input, I press Enter key, nothing happened. Finally, I found when I remove Chrome's plugin 1 Password, the message shows.
After debug, yyx990803 gives out the reason. It's
1Password plugin's bug. The plugin thinks the input named
grant_type with the value
password is the password form input(while it's not), so we can focus on
grant_type input and press
enter key, after that, the form submitted.
