What I expected to happen was...:
I would be blocked by the end rods and not be able to go on them
What actually happened was...:
I walked onto the fence's hitbox first, then up onto the fence
Steps to Reproduce:
1. Place (any type of) fence
2. Place end rod on top of fence
3. Place block next to fence
4. Walk on block and onto fence
5. Walk onto end rod
WAI. Fence hitbox is 1.5 block heigh. End rod and other blocks with 1 block height on fence give 2 block of height. You can walk half block up without jumping (from 1,5 to 2,0).
