Scenario: Alternative Loop Paths with single node path
@mld-only
Scenario: Alternative loop paths on a single node with an asymmetric circle
# The test checks only MLD implementation, alternatives results are unpredictable for CH on windows (#4691, #4693)
Given a grid size of 10 meters
Given the node map
