lingering potion starts a big fire when thrown in lava

What I expected to happen was...:
no fire just the potion smoke of the lingering potion

What actually happened was...:
the smoke of the lingering potion by being a entity catch on fire what make a big fire image

Steps to Reproduce:
1. place some lava anywhere
2. throw a lingering potion except water, akward or mudane in the lava
3. see by a view point except the view by the up
