Description
When we updated our Nextcloud instances from NC 31.0.14 to 32.0.6 last week, a bunch of board shares went missing.
Reproducing it, the shares are removed from the oc_deck_board_acl table on the first cronjob run after the upgrade, and it seems to involve only boards that are shared with circles that have circles as members themselves (yes, that is possible apparently).
It doesn't seem like the DeletedCircleCleanup migration is at fault, as there's no "Removed circle with id" messages in the logs.

Research direction
Start by reproducing the upgrade from Nextcloud 31.0.14 to 32.0.6 and inspect the first cronjob run, focusing on deletions from the oc_deck_board_acl table. Read the DeletedCircleCleanup migration and compare its behavior for boards shared with nested circles. Done means those board shares remain present after the upgrade and cronjob run.
