The bug
When placing a piece of redstone downward and to the side from another piece of redstone, the one on top stays in its original orientation and doesn't turn into the correct orientation.
How to reproduce
Place two pieces of redstone in a line, and place another piece down one block and to the left or right.

Seems to be fixed in 1.13-pre8. Can others confirm?
I can confirm that it is fixed in 1.13-pre8.
I think the problem here is that the upper redstone wire isn't getting a block update when the lower wire is being placed.
