Players remain crawling while intersecting a non-full block

The bug

Players who are crawling will remain crawling as long as they intersect a non-full block (e.g. trapdoor), even if there is room to stand up.

How to reproduce

1. Place two trapdoors using the following commands:

   /setblock ~ ~1 ~ oak_trapdoor[half=top]

   /setblock ~ ~ ~1 oak_trapdoor[open=true]

2. Stand near the lower trapdoor:

   /execute align z run tp ~ ~ ~0.9

3. Open the upper trapdoor
   → ✔ You begin crawling

4. Close the lower trapdoor

5. Destroy the upper trapdoor
   → ❌ You remain crawling
