The backgroundColor of the embed has a hexcode of "#2f3136". When a user types "transparent" in the color inputfield it will be replaced with the background hexcode to make it look like the border is transparent.
It's not really transparent as it doesn't work on light theme nor any type of custom theme, so disguising it as transparent is misleading. As such I don't really want a thing like this built into the site.
