Hi,
when moving the end node of a line and reversing it, you can reach a state where the normally parallel orientation of line and symbols breaks.
Bug, feature, or Easter egg?
Only visible with really large stroke settings.
If you reduce stroke, effect collapses at some point.
Image shows a copy, then using node tool to re-arrange one of the nodes (going from e.g. 100 to -100, crossing the other node in the process).
