Slab autoplacement bug

So the issue is that when I have a line of slab blocks and try to make them double slab blocks by holding down L2 it doesn't work but doing the same on a full block works fine, it really slows down building time.

Steps to Reproduce:

1. Place line of slabs, amount does not matter
2. Try making the slabs full blocks by holding the place button and moving along the line

Observed Results:
The auto placement will fail, making you have to place it by tapping the place button instead.

Expected Results:
The auto placement should've worked like how it intended to work.
