Big Dripleaf can conduct redstone

Summary
Big Dripleaf can be used to conduct redstone to power things like pistons, redstone lamps, and other redstone blocks/items. This is inconsistent with Java, where it doesn't conduct the redstone at all. This was featured on silentwisperer latest bugrock video, and I was surprised that it wasn't reported here.

Step to Reproduce
1. Build the contraption like in the screenshot.
2. Flick the lever.
---> The big dripleaf conducts redstone.

Expected Results
It should not conduct redstone
