Instead of using text-shadow you can just use filter: drop-shadow(1px 1px 2px #333); on the #chat_container and it supports drop-shadow for 7tv paint names and also emotes which are both impossible with the text-shadow css currently used.
So essentially I recommend changing from using text-shadow settings to using the drop-shadow filter instead for better support.
