Hay bales generating on paths in villages do not convert the path block to dirt

Hay bales generating on paths in villages do not convert the path block to dirt

 

What I expected to happen was...:
When the hay bale generated, I expected the path block underneath to be converted to dirt
 
What actually happened was...:
However, the path block remained and allowed for a gap between it and the bale. Block updates to either did not change the path block (excluding breaking either)
 
Steps to Reproduce:

1. Go into spectator mode
2. Observe the Hay bales
