Describe your issue

The dark: prefix only works on bg-color, but will not hide div that contains <img/> tag or image itself.
The div will be hidden if it doesn't contain an img tag, or if the div is not the img tag.

Hey! You need to enable the dark variant for the display plugin, it's not enabled for all plugins by default.
