Losing bond stereo on molecules

[mwojcikowski]

RDKit-js loses double bond stereo when generating molblock

var smiles = "F\C=C\F";
var mol = RDKitModule.get_mol(smiles);
var mol2 = RDKitModule.get_mol(mol.get_molblock());
console.log(mol2.get_smiles())

This will produce: FC=CF

Expected behavior
produce: F\C=C\F

Debugging
Produced molblock is wrong, it does not contain bond stereo information

In python the molblock is good Chem.MolToMolBlock(Chem.MolFromSmiles('F\C=C\F'))

Turns out that is the issue with escaping... Following works correctly!

var smiles = "F\\C=C\\F";
...
