I would suggest making this suggestion using the "help" function in the lower left.
Dark Mode Dropdown Options Not Shown

Heyo! I thought this issue was just a quirk of my computer, but after testing Chess.com on Chrome without any extensions potentially causing issues, it seems that dark mode doesn't change HTML <select> (drop-down box) option text colors to something visible. The color of the options get changed to the background color of the drop-down, meaning you can only see the options individually as you hover over them (example). This doesn't occur in light mode (example).
I'm guessing the intention was to rather change the drop-down's background to a dark color, since dark mode includes CSS for the options to change their color. It's not a huge deal, but it's definitely something that could improve user's experiences.
Thanks, and gl hf!
It's a known bug and has something to do with Chrome using OS inheritance if an explicit background isn't set in dark mode. It was a change in how Chrome does things.
Firefox Developer has a similar issue but it is a browser based inheritance and looks like
