Dear Maintainer,

I have a user which I don't want shown in the greeter.

I included it in the HideUsers= setting. But it exists because it is
sometimes used to log in, via SDDM, by people who know the username.

In a recent version (I'm on testing, 0.21.0+git20260819.da0b64d-1),
after the login is used, the user is shown (and even selected by
default). I haven't seen this before. After another user logs in, the
hidden user is hidden again. This was not the behavior in older
versions, but I am not sure when it was introduced.

RemeberLastUser= was set to true, as the default. I have now set it to
false as a workaround.

Reported upstream as https://github.com/sddm/sddm/issues/2234, posted
here only for tracking.
