web-greeter with litarvan theme doesn't remember my choices correctly

[lakejason0]

Environment

• OS: Arch Linux
• web-greeter version: 3.5.2

Bug description

In other greeters like sea-greeter or the obsolete Antergos', Choosing Plasma (X11) or Plasma (Wayland), or like other settings' options is remembered after logging out. However in this greeter this is not correctly remembered, and it takes twice and more times of logging out to be remembered. gruvbox didn't seem to have this problem I suppose? Haven't tried it out though.

Steps to reproduce

• Extract the master branch of Litarvan theme to /usr/share/web-greeter/theme/litarvan, then set the theme in the yaml file.
• Choose "Plasma (X11)", then log in then log out or reboot.
• The option goes back to "Plasma (Wayland)". Choose "Plasma (X11)" again. Repeat.
• The option is now remembered as Plasma (X11).

This may be a Litarvan's issue. I tested this in web-greeter, nody-greeter, and this happens in both. However, as you pointed out, sea-greeter remembers the choices. Though, gruvbox and dracula themes does not present this issue.

I will investigate it further.
