Summary
Player catches fire when riding a Strider and stepping off a platform above lava.
Steps to Reproduce
Go to the Nether.
Place a small platform 3 blocks above a lava lake.
Ride a Strider using a warped fungus on a stick.
Move forward and step off the platform to descend toward the lava.
Expected Result
The Strider should safely descend onto the lava surface without the player taking fire damage.
Actual Result
As soon as the Strider steps off the platform edge (before touching the lava), the player instantly catches fire and takes rapid damage as if inside lava, followed by normal fire damage. This happens even though the Strider is supposed to walk on lava.
Additional Notes
It feels like the game incorrectly detects the player as being inside the lava before the Strider reaches the surface. The Strider does not visibly sink, and the fire starts before any collision with the lava.
The issue with the player catching fire before the strider touches the lava is tracked at (MCPE-179969).
With regard to the present report, I could only reproduce this dropper from 3 blocks or higher, not 2 blocks, and I believe the player’s collision box does enter the lava even though visually the seat may be just above the lava. The visual position of moving entities is not accurate due to (MCPE-179969).
