The change "Added new logic for mobs dismounting rideable" breaks the minecart logic and boat exiting.

The following issues occur:

• A player in a minecart going over an activator rail with solid blocks at a head height will suffocate, because the minecart prefers to put the player inside of solid blocks instead of on trapdoors, water, or a safe fall next to the track (see Mine cart Murders me.mcworld ).
• Minecarts going over activator rails no longer drop mobs into holes, ruining many mob farms and villager transport systems.
• It doesn't fix the issue with the boat, as you fall through when you get in water. Fall through boat.mp4 (MCPE-105535)
• It doesn't fix the issue on the strider on going into lava.

I am unclear on what this actually fixes as the stated fixes are not actually not fixed and the the player/entities end up often put into more hazardous locations IE inside of blocks causing suffocation damage.

This is a regression that actually causes death in more condition then it prevents.
