[2021] Do I get experience for burning zombies with molotov cocktail?

In my experience, There seems to be a timer that measures the last time you interacted with a zombie- If it dies after that point via fire or bleed, then you get no exp. So following that line of logic, if you're literally only setting them on fire and then not engaging them any further as they burn to death, then you won't get exp as it's been too long since you last hit the zombie and the game essentially has determined that the zombie died to environmental damage- Not due to the players action. (The fire debuff from all sources is the same; be it player caused or campfires, or burning barrels.)
