This should be fixed as bsc#957018, please retest by installing updated
os-prober package from maintenance update after the mentioned fix released
(which is not yet at the time of writing).

Out of curious, how did you do that ? Is it chainloading the btrfs partition ?

Please consider it as os-prober limitation, currently it will ignore snapshots
except default subvolume.

Thanks,
