when configuring a global pipeline library "Default version" retrieved from "Modern SCM" -> "Helix Library", I would expect that "#head" should work for the latest "Library Depot Path"

entries like "master", "#head", "head" either don't validate or evaluate to version "-1" (resulting in "@-1" in p4 operations)

the only way to get the latest on the path is to specify a huge number inexorably greater than any version in the repo (e.g. "100000000000")
