Power Levels not monitoring blocks correctly

[wrincewind]

i've noticed that the texture on the Power Level block is not updating to reflect the power level of its input block - but it will update based on a block on a different side of it.

(note that i'm facing north in this screenshot)
however, this does not effect redstone output - that's pulling from the block as usual, it's just the number that's wonky.

This is based on the latest MultiWorkspace 1.16_tech build.
