Skeleton horse and zombie horse do not burn in the daytime

Isn't it a suggestion?

Not really, they are classified as undead, and so it's expected they burn in sunlight.

Unless he is a Wither Skeleton Horse. 🙂
But he is white. 😛

Yes, I can confirm this and would respectfully request that this be changed soon. They are multiplying out of control and are clogging up everything. The one server I am on is being overrun by these things, piling up in holes or any open area, and making it hard to move around unless you take quite a bit of time to just get rid of them, like ten to twenty minutes a day, cleaning up areas over grown with these creatures.

Thanks!!!

so, each of these are a week apart, but are only after a 24 hour period from the last time I "cleaned the area up". Its like a bunch of bugs crawling out of the woodwork.

They don't burn in sunlight for the same reason spiders don't.

This is working as intended.

But in Minecraft, all zombie variants burn. Same with skeleton variants. This is not WAI.

I am able to confirm this behavior in 21w38a. Here are some extra details regarding this problem.

The Bug:

Skeleton and zombie horses do not burn in the day.

Steps to Reproduce:

• Summon both a skeleton and zombie horse.

/summon minecraft:skeleton_horse ~ ~ ~
/summon minecraft:zombie_horse ~ ~ ~

• Ensure that the time is set to "day".

• → ❌  Notice how skeleton and zombie horses do not burn in the day.

Expected Behavior:

The expected behavior would be that skeleton and zombie horses would burn in the day.

Can confirm in 1.18.1.

"Fixing" this would render skeleton horses almost completely useless, since they wouldn't be able to be ridden during the day. It would also make getting them much harder, since they'd probably burn up while trying to kill the skeletons. And it doesn't fix any problems; it's not as though skeleton horses are common, or aggressive. I get that it makes logical sense, but it's not a good change. 

Unless horse armor prevents them from burning while remaining unbreakable, and skeleton horses spawn with armor on. Which could be cool, I guess. 

Can confirm in 1.18.2 and 22w18a.

Can confirm in literally every single version.
