Jumping and/or walking on an edge aboce lava often results in the player catching on fire.

If walking or jumping to a block thats above lava (even if its multiple blocks up), there's a chance that if you go slightly past the block or short of the block and still make the jump, that you'll be caught on fire. This is shown in the videos below. And it's not from the ghast fireballs either (for I have tested this in other circumstances). I would love to have this fixed because it's much harder to play in the nether and make lava-themed obstancle courses like the one shown in the video. Thanks.
