Steps to Reproduce

1. Add to Canvas cascade reaction with the same product and reactant with Multi-Tailed Arrow or/and usual Arrow:

• This case must be automated after fix;
• Issue is detected during exploratory testing of Load RDF feature for cascade reactions - Position single elements and reactions, not included to the first cascade reaction #2102
