Thanks for this hint. I added the -s flag, but I can still reproduce the
snapshot removal problem:

lvremove --verbose -f plana/snap_web
    Using logical volume(s) on command line
    Archiving volume group "plana" metadata (seqno 1137).
    Removing snapshot snap_web
    Found volume group "plana"
    Found volume group "plana"
    Loading plana-domu--web table (253:1)
    Loading plana-snap_web table (253:9)
    plana/snapshot0 already not monitored.
    Suspending plana-domu--web (253:1) with device flush
    Suspending plana-snap_web (253:9) with device flush
    Suspending plana-domu--web-real (253:10) with device flush
