Steps to reproduce the problem:
1. Go to the sign-in screen
2. Enter a password
3. Instead of pressing ENTER, close the laptop's lid

What is the expected behavior?
The password field should automatically be cleared, as it is in other platforms such as MacOS in this situation.

What went wrong?
The password entry stays in the field, even if the laptop has been closed for many hours.

The expected behavior is that closing the laptop's lid should always put the laptop into a secure state -- automatically locking or logging out. In the case where the user enters their password, but then decides to abandon the sign-in before they hit Enter, the laptop is left in an insecure state with the lid closed (someone who found the laptop hours or days later could open the lid and sign in without knowing the user's password.)
