Put the summary of the bug you're having here
The iron trapdoor was apparently hanging in the air, but it was catually on tyhe other side
What I expected to happen was...:
The trapdoor should fix itself when the redstone updated it
What actually happened was...:
it sprite broke- when turned off, it was correct, but when on, on the wrong side.
Steps to Reproduce:
1. Have a iron trapdoor from a previous version
2. update it
3. the trapdoor image will be in one side and the actual trapdoor in the other
Fixed for a future version. MC-59946
