      Steps to Reproduce:

      1. Open a world in version 1.21
      2. Build a small open-topped enclosure where at least one wall is two-high trapdoors. For the sake of easier explanation, let's make this the east wall, but this is not a single-direction issue.
      3. Press F3 to bring up the debug screen. Check the orientation of your trapdoors. For the east wall, they should be labeled "facing: west" and "open: true". If not, break and replace them in the correct orientation.
      4. Spawn a horse inside the enclosure.
      5. Observe the horse.

      Observed Results:

      In version 1.21, the horse will eventually attempt to go through the trapdoor wall and, being unable to just walk through, start jumping. It will jump very high, likely to the full extent its jump stat allows. Jump height varies between horses, but most will be able to jump over the trapdoors and leave the enclosure.

      Expected Results:

      In version 1.20.4 and other previous versions, the horse would also try to go through the trapdoors and wind up jumping. But the jumps would be low-power, ordinary single block jumps such as a cow would do in the same situation. The horse would remain in the enclosure.
      Even in version 1.21, the horse will still remain inside an enclosure with trapdoors facing the other way ("facing: west") and consistency between the two is expected.
