Updating vines with all directions set to false from versions before 17w47a (1.13 snapshot) break upon loading in that version and further. This issue still persists in recent version.
Steps to reproduce:
1. Load a world in 1.12.2
2. Execute command /setblock ~ ~ ~ vine
3. Update the world to 17w47a or further (except versions affected by MC-239856, explanation in comment)
Expected result:
vine does not break
Observed result:
vine breaks

This bug isn't a duplicate of MC-239856 for 2 reasons:
much different version range of this bug occuring; MC-239856 occurs by updating from versions around 1.11.2 (probably just pre The Flattening) to current version (maybe few snapshots back) while this bug occurred always by updating from version before 17w47a to 17w47a or higher.
different affect on vines; MC-239856 sets all vines' "up" state to "true" while this bug makes all directionless vines just break.
