commit d866bb51927b8b75718438a63138834bb7ea2f6c

    tdf#88555: band-aid fix, using GetPos/find instead of Contains
    
    to find out whether given format still exists.
    
    GetPos was replaced by Contains on multiple places in commit
    98436c4b53639d86f261ac630c46d32e3c7b8e28 but sometimes after
    series of undos/redos, vtable of some items in those format arrays
    becomes corrupt and it makes dynamic_cast (as used by Contains)
    fail and Writer falls flat on its face.
    
    This is just a workaround, no idea about the root cause.
