Reactions change the ordering on canvas after layout or save/load to/from RDF actions

[ivanmaslow]

Steps to Reproduce

1. Add 2 reactions with Multi-Tailed Arrow and single arrow with shifted positions:
   
2. Click on Layout

Actual behavior

• The first reaction becomes the second:
  

Expected behavior

• The first reaction should be the first as it was before layout action

Environment details

• Detected on CI-CD environment with 2309-update-layout build
• Ketcher [Version 2.25.0-rc.2] Build at 2024-09-30; 06:32:00
• Version 1.25.0-dev.2.6-g0e1cfa10-wasm32-wasm-clang-12.0.0
• Desktop, Windows 11 Enterprise
• Chrome Version 129.0.6668.71 (Official Build) (64-bit)

Notes

• Pay attention, that it should be tested for saving to RDF as well and should work as expected;
• Issue is detected during exploratory testing of Import/Export for Multi-Tailed Arrow in cascade reactions - Import/export multi-tails in KET #2236

Priority was changed to Medium as this case is not critical for initial requirements: more then one reaction on canvas.

Pre-tested on aws_ci environment with Ketcher master and Indigo 2407-branch-ordering branches:

• Ketcher [Version 2.26.0-rc.1] Build at 2024-10-24; 12:25:38;
• Indigo Version 1.25.0-rc.3.18-gcdee98d4-wasm32-wasm-clang-12.0.0
• Desktop, Windows 11 Enterprise
• Chrome Version 130.0.6723.70 (Official Build) (64-bit)

Fixed for case in the defect:

But in case of a bigger quantity of reactions, it can be reproduced on layout or save/load to/from RDF - ordering is changed for reactions:
