The work done in #41799 was not complete and needs to be repeated for administrator\components\com_users\tmpl\captive\select.php

@wilsonge
I just discussed with @coolcat-creations about this issue. She mentioned that you fixed a lot of issues with dark/light mode in your PR #41799 and that this issue might be an easy PR for you.

I basically repeated what @brianteeman said ;)

I am getting married tomorrow so unlikely to do this any time soon. Sorry!
