      Description

      The bug

      When you have a nogravity boat (on level for example 65 and a block on level 64), and you ride that boat into the block (reproduced on various speeds), the boat sometimes (like 10% - 30%, does it more on higher speeds) briefly glitches out, and views the block below it as a barrier - however when you stop ramming into it - it lets you go through.
      The following warning is logged:

      Boat moved wrongly!
      

      And than the JVM crashed (possibly unrelated): https://pastebin.com/raw/Ep2mtycL

      How to reproduce

      1. /fill ~-1 ~ ~2 ~2 ~ ~5 blue_ice
        
      2. /fill ~ ~ ~3 ~1 ~ ~4 air
        
      3. /execute align xyz run summon boat ~1 ~1 ~2.5 {NoGravity:1b}
        
      4. Drive accross the ice multiple times
        A few times the boat will act as if it collided
