Shouldn't the above line already handle this edge case? I'm a little bit confused at what needs to be fixed here

Oh wait, I see what you're going for. You might need to move it above the check for URL.isUrl though, I'll test it out later.

i've just made it so it's the same logic as the embed option

the point is so that if you type something like discord.com it will add http:// before it, so that UV doesn't say invalid url
