Upgraded from F39->F40 via dnf upgrade mechanism.

During first boot after upgrade, I hit Esc to see the service startups to monitor for any issues.

My /home partition is encrypted by LUKS.  

I get the normal prompt that looks like:

Enter passphrase for /home on ####: <enter password here>

When I do that, instead of nothing (or *s), I see my password in plain text.

After hitting <enter> I see an echo'd out statement:
Enter passphrase for /home on ####: ***** (number of *s equal to my password length)

This is 100% reproducible if you have an encrypted disk here. 

Boot process, after selecting kernel to boot into F40, hit escape to watch non-GUI boot process. When asked for passphrase for encrypted partition, enter it and hit <enter>.  You'll see your passphrase in plain text, then a repeat of the prompt with *'s immediately afterwards.

Note: This did not occur on F39.

Reproducible: Always

Steps to Reproduce:
1. Have an encrypted partition setup
2. Reboot system
3. Select kernel at GRUB and press enter
4. Hit <Esc> to watch services start up instead of the nice GUI
5. Enter passphrase when prompted
Actual Results:  
You see your passphrase in plain text

Expected Results:  
You should see nothing or *s
