Nether sprouts don't drop with silk touch

The block only drops if broken with shears, like grass. It's intended.

I was pretty sure silk touch can get any block no matter the tool

No. Can you mine obsidian with a silk touch wooden pickaxe?

Thank you for your report!
However, this issue is Working as Intended.

You now need to use shears to get an item when breaking Nether Sprouts.
