Another case where freestyle input properties need to be sanitized (#89081 (Freestyle seed in noise modifier can be zero (leading to crash)) is another case).
Should just be forced to positive / non-zero.
Not sure if it mandatory to have a version patch in do_versions for this, but will check on these.
