[ivanmaslow]

Steps to Reproduce

1. Open in Ketcher one of valid .ket files (6 different cases) with saved Multi-Tailed Arrows:
   Zip.zip

Actual behavior

• Error message is displayed
  

Expected behavior

• No errors, elements from .ket file are displayed on Canvas
  TBD - fixed-point precision (4 decimal places)?

Environment Details

• Ketcher [Version 2.25.0-rc.1] Build at 2024-09-03; 15:31:03
• Indigo Version 1.24.0-rc.1.0-gb8f099851-wasm32-wasm-clang-19.0.0
• Windows 11 Enterprise

But the logic of movement tails is broken - the user can move tails closer than 0.35 to each other:

Also some smoke checks were passed successfully for Multi-Tailed Arrow: selection, movement of arrow itself, changing of size and position of head, changing positions of top and bottom tails, changing size and positions of added tails, removing of tails, copy/cut paste, undo/redo actions, deletion of Multi-Tailed Arrows
