* [NO GBP] Fixes hoverboard being able to be used in space. (#84533)
## About The Pull Request
Apparently I've left out that `isopenspaceturf(A)` returns false on
normal (not multi-z) space turfs because they're of a different path.
This should fix the fact you can use hoverboards as a substitute
jetpacks, which wasn't intended. You can still use them in space if
there's lattice/catwalk underneath, or another kind of turf on the
z-level below however.
## Why It's Good For The Game
Unintended bit from the skateboard buff PR I had made months ago.
## Changelog
🆑
fix: Hoverboards properly dysfunction in space without any kind of
support underneath them.
