Burning zombies are not extinguished by splash / lingering water bottles

The zombie that burns from the fire obtained from flint or from the light of the sun and then passed to / time set night continues to burn even if it launches a launchable or persistent potion of water causing its death (if with little life). Instead with the whole life the zombie burns up to a certain time then turns off by itself, but if you try while burning to throw a water potion at it continues to burn.
