Background color, or highlighting, for UDSelectOption items

Another, hopefully easy, question. I have a UDSelect that allows for multiple selections on a form that I haven’t used in a long while. Running it now under the latest update, I noticed that if the page is in light mode you can no longer see the options selected in the dropdown (they do show up as expected in the Select box). You can, however, still see them if in Dark mode (see below). Just curious what the best practice way would be to get around this? Is there an easy option to change the background color for the Select, or would I need to create a Style and apply it to this element?
