Redstone wire with custom model unexpectedly appears green

The bug

With my custom model for redstone wire, vertically moving wire with a power level of 15 and without any other full blocks adjacent to it other than the one it's climbing appears green at the very top. I believe this change may be due to the newly added emissive textures in 24w33a, which I've adapted it to use.

How to reproduce

1. Download and apply the attached resource pack
2. Place redstone moving up the side of a block
3. Power it with level 15

Expected results

Redstone would be red.

Actual results

There is a gradient to green.
