SMILES output does not retain stereochemistry information

[AndreiMazol]

Steps to reproduce:

1. Convert SMILES O=C(O)[C@@]([H])(N)C string to Mol by executing convert or layout endpoint
2. Convert resulted Mol string to SMILES (convert endpoint)

Actual result:

1. Resulted SMILES is O=C(C(C)(N)[H])O instead of O=C(O)[C@@]([H])(N)C
2. convert & layout endpoints returns different results

Expected result:

1. Resulted and original SMILEs are equal
2. Layout & Convert returns the same Mol files

[AlexanderSavelyev]

the molfile is generated correctly into S-isomer. So the issue is related to Ketcher Daylight SMILES saving

[AndreiMazol]

After converting resulted mol file to Extended SMILES the result is O=C(C@(N)[H])O instead of O=C(O)C@@(N)C
