Description:

true/false settings in the admin UI can't be switched back to their original states (once the "Save" button is clicked) unless the page gets reloaded. I tried with Accounts_Default_User_Preferences_hideUsernames and Store_Last_Message, so I'm certain it's not only those from the "Accounts" section.

Steps to reproduce:

1. Go to admin UI → Accounts → Default Preferences
2. Set "Hide usernames" to "true"
3. Click "Save"
4. Set it back to "false"
5. Notice how you can not click "Save" again

Expected behavior:

Save button should be clickable

Actual behavior:

Save button not clickable
