Steam Cloud not working with FreeBSD Wine

[i-lost-my-bagel]

When launching games with FreeBSD Wine/Proton, steam cloud save files don't appear.

Tested with stardew valley and balatro.

Steam cloud saves work with linuxulator proton.

I've tested this briefly with 38740 and sync seems to work for me (at least from one FreeBSD machine to another FreeBSD machine), so not sure what could be done there.
