Input field doesn't see the password has been filled up

[Combinatix]

This issue is most annoying on the forms where the Submit button remains disabled until the password input field has changed, or two password fields that require password verification.

1. When I place the cursor into the empty input field and then I press the Use Password button, the browser does not see the password has been filled up. The submit button stays disabled.

2. In case of two password fields (New password and Verify password) the browser does not see that both passwords are the same and/or filled up, when using the Use Password button

The same issue is with the context menu Generate password or Insert previous password. In both cases I have to use Copy / Paste password to get around this issue.

I think it has something to do with JavaScript, which doesn't see the keypress event or something similar. Example site is https://id.arduino.cc
