Wetness level for undead mobs

I think that if a drowned or something comes out of the water, they should dry before burning. Let's look at it this way:

A skeleton is attacking you in the day time, but isn't burning because it's in water. You try to escape it, but it follows you out the water and instantly starts burning. If that was me in this situation, I'd think to myself why is it burning? It's wet!. So, to change this, I'm offering wetness.

When an undead mob is wet, it takes a while for it to burn depending on the biome it's in while it comes out of the water. In a cold biome, it takes 2 1/2 minutes for it to dry? And then it starts burning, or it doesn't burn. That's up to you (the devs). If in the plains, it takes, I don't know, 45 seconds? In a desert, it'll take probably 10 seconds. Et cetera.

If this gets added, then feel free to change the times around.
