Fire Resistance should make lava translucent when you're submerged in it

As the title suggests, I believe that fire resistance potions should make it possible to see in though lava when you're swimming in it. not completely transparent but closer to the way water is normally.

Not being able to see though lava when swimming in it is a long time mid-end game annoyance. adding this simple feature would be a small change that would go a long way towards making building in the nether a lot more pleasant.
