Describe the Bug

The mod "Just Vertical Slabs" adds vertical slabs generated from every slab in the game, using only two block IDs, by using some sort of extra data that isn't kept in the blockstate as far as I can tell. One issue that arises from this is that the schematicannon doesn't seem to understand this extra data.

Holding a schematic to view a preview works fine, and all slabs show correctly, but loading the same schematic into a cannon, even with a creative crate next to it, will cause any JVS slabs placed by the cannon to have the default no-data oak texture they use as a fallback, and "corner vertical slabs" seem to break entirely, rendering a hole in the world instead of a texture and with the wrong hitbox. They seem to not be placed with the extra data they're supposed to have.

Reproduction Steps

1. Build something using Just Vertical Slabs' Vertical Slabs
2. Create a Schematic of the area using Schematic and Quill
3. Place a Schematicannon with a Creative Crate
4. Active the Schematicannon

Expected Result

The expected result would be for the schematicannon to place the block as copied into the schematic.

I haven't used that instance or mod in years, but thank you, I'll keep that in mind for future reference.
I assume I can also add blocks to that tag via datapacks if a mod author hasn't done it themself?

if the data is kept in nbt then the more author for the slabs your using needs to tag them with create:safe_nbt (block tag)
