Description
**Steps to Reproduce**
Following structure generates R CIP label

While indigo clearly reports that there is an error in stereochemistry

**Actual behavior**
Wrong CIP label being presented
**Expected behavior**
There should be no CIP label. The molecule should also not be marked as ABS chiral at all, as it is symmetric.
**Ketcher version**
Ketcher Version 2.7.0 Build at 2023-01-31; 13:58:49
Indigo Toolkit Version 1.9.0.0-g14d7413c3-wasm32-wasm-clang-13.0.0

Research direction
Start by reproducing the reported structure and comparing Ketcher's displayed CIP label and ABS-chiral state with Indigo Toolkit's stereochemistry error. Trace the CIP and symmetry handling used for this case, then add a regression test showing that the symmetric molecule receives no CIP label or ABS-chiral designation.
