Can't correctly save specific cascade reaction with 3 tails to RXN/RDF

[ivanmaslow]

Steps to Reproduce

1. Add cascade reaction from ket:
   ket-cascade-reaction-tails-5-with-pluses (1).zip
   

2. Click on Save as...

3. Select RXN or RDF

Actual behavior 1 - Save to RXN

• Reaction 7:7 is displayed on preview because all reagents are united and all products are united:
  

Expected behavior 1 - Save to RXN

• Only root reaction 1:2 is on preview and can be saved to RXN

Actual behavior 2 - Save to RDF

• Reaction 7:7 is displayed on preview because all reagents are united and all products are united:
  

Expected behavior 2 - Save to RDF

• Set of separate reactions can be saved to RDF

Environment details:

• Ketcher [Version 2.26.0-rc.1] Build at 2024-10-04; 18:45:04
• Indigo Version 1.25.0-rc.1.0-g704673fcb-wasm32-wasm-clang-19.0.0
• Desktop, Windows 11 Enterprise
• Chrome Version 129.0.6668.100 (Official Build) (64-bit)

Additional context

• If you remove the second tail, cascade reaction can be correctly saved to RDF and loaded from RDF:
  
  
• Issue is detected during exploratory testing of Save multi reactions (pathway, single, edge cases) to RDF #2237

The issue isn't reproducible on the latest RC SA env:

• Ketcher [Version 2.26.0-rc.6] Build at 2024-10-25; 09:57:12
• Indigo Version 1.25.0-rc.4.0-g8862ccb7e-wasm32-wasm-clang-19.0.0
• Desktop, Windows 11 Enterprise
• Chrome Version 130.0.6723.70 (Official Build) (64-bit)

Probably it was fixed together with #2454.
Reaction can be correctly saved to RXN/RDF:
