Additional Context

On initialization, the following code is executed:

        if emoji is not None:
            if isinstance(emoji, str):
                emoji = PartialEmoji.from_str(emoji)
            elif isinstance(emoji, _EmojiTag):
                emoji = emoji._to_partial()
            else:
                raise TypeError(f"expected emoji to be str, Emoji, or PartialEmoji not {emoji.__class__}")

Which is not executed when doing the_select_option.emoji = "🔴".
