Bold lines for complexes

I noticed changing to bold lines (3px?) for complexes in MINERVA vs. normal lines in CellDesigner. Should it simply match CellDesigner's thickness?

If the original diagram has 1px, it can create unexpected effects with 3px. For example, for this diagram it created kind of a mess in the top-right corner. The lines look too close in MINERVA: https://mreg.elixir-luxembourg.org/minerva/index.xhtml?id=glycogen_LL05_liver. For AsthmaMap works but then it was designed with 2px for complexes, though now in MINERVA it is more like 3px.
