[MCPE-125386] Foxes sleep/don't move on lower half slabs

When trapped on lower half-slabs foxes will just stand/sit around and fall asleep as well.

Since my video exceeds limits I will leave a Google drive link to my video.

New video added in the folder showing the bug in the 1.17.10.20 beta

Steps to reproduce:

1 build a box

2 Put half slabs on the bottom

3 Add foxes

Observed results:

Foxes sleep at anytime

Expected results:

Foxes should still be awake at noon
