After the new update issue with the language selector dark mode

Hi, I hope you are well.
After the latest update I discover now the language selector is always white also when the dark mode is active.

The CSS code you given to me in the past that was working, is no working anymore.

html.wp-dark-mode-active .switcher .selected {
    background: #134140  !important;
}

html.wp-dark-mode-active .switcher .selected a {
    color: rgba(171, 187, 215, 0.95) !important;
}

Can please help me to understand what CSS need to activate this element (translation language bar on bottom right) for be included in the dark mode?

Thank you.

I tried also a suggestion here:

html.wp-dark-mode-active div.gt_selected {color:#eee;background:#333;}

but is not working.
