Inconsistent behavior of copy-paste and cut-paste operations with macromolecule abbreviations

[Zhirnoff]

Steps to Reproduce

1. Open file in Macro mode (Flex mode) not-cycled-sequence.zip
2. Switch to Micro mode
3. Select all abbreviations and copy/paste
4. Repeat p.3 for cut/paste

Actual behavior
Some macromolecule abbreviations are copied or cut correctly, while others are not included in the operation.
This inconsistency leads to partial copies or cuts, with some abbreviations missing after the paste operation, making the workflow unreliable.
Sometimes errors appear in the DevTool console.

Expected behavior
All selected macromolecule abbreviations should be copied or cut and pasted consistently, maintaining their original structure and positioning.
