Ketcher part: Micro and macro structures connected through attachment points cannot be opened after save in CDXML format in micro mode (in MOL it opens slightly wrong structure))

[AlexeyGirin]

Original issue was created in Indigo - https://github.com/epam/Indigo/issues/1993 @even1024 told that he did his part and now it require Ketcher side change to be done. As for mol format - it doesn't create corrupted file (it is possible to load) but resulted molecule is wrong

Summary Micro and macro structures connected through attachment points cannot be opened after save in CDXML format in micro mode

Steps to Reproduce

1. Open Ketcher.
2. Draw a benzene ring
3. Add an attachment point to the benzene ring via right click menu
4. Switch to Macro mode and connect attachment point to a macro structure
5. Switch to Micro mode
6. Save structure in CDXML format
7. Open saved file

If it is not possible to draw the structure, then you can open the prepared file (you just need to open it in macro mode and then switch to micro mode): ketcher (53).zip

Expected behavior Micro and macro structures connected through attachment points can be opened after save in CDXML format in micro mode

Actual behavior Micro and macro structures connected through attachment points cannot be opened after save in CDXML format in micro mode
