Redstone torches stay floating when the block that it is attached to is destroyed

Redstone torches stay floating when the block that it is attached to is destroyed. This happens for me when the torch is on the side of a block. This seems to just be a simple block update bug.

What I expected to happen was:
I expected the redstone torch to 'pop' off of the block that it was attached to when the block was destroyed

What actually happened was:
The redstone torch stayed floating in the air air

Steps to Reproduce:
1.Place any block down that a redstone torch can be attached to
2.Place a redstone torch on the side of that block
3.Destroy the block that the torch is attached to
