Default Account Creation Page not Keyboard Accessible

The default Moodle account creation page is not accessible to keyboard-only users in Google Chrome. The link/control that must be activated to display the password field(s) cannot be activated using only the keyboard. It is possible to set focus on this control using Tab but the field does not appear upon pressing Enter.

This issue is not present in Firefox.

Instructions:

1. Open a default Moodle create account page in Chrome. Example: https://accessibility.mrooms.net/login/signup.php  
2. Attempt to complete the form using only the keyboard.
3. Tab to the "click to enter text" in place of the password field and press Enter.
4. Note the field does not expand upon pressing Enter.
