Layout of molecules problem and error appears when use "Add/Remove explicit hydrogens" button secondary times.

[NadezhdaPeskun]

Steps to Reproduce

1. Open [Indigo Toolkit] Version
2. Open Structure icon >> select Open from file
3. Select attached "2024-02-29_10ketcher.mol"
4. Open to Canvas button
5. Press Add/Remove explicit hydrogens button several times as on the 2024-02-29_10h37_57 attached file

It may be a duplicate for https://github.com/epam/Indigo/issues/1576 but example is less complicated Task https://github.com/epam/Indigo/issues/1436

Expected behavior Hydrogens should be added and removed using the button in any iteration.

Actual behavior Molecules layouts are changed, and error message is appeared.
