Molecule rendering overlaps

**Steps to Reproduce**
While rendering SMILES from list attached overlapped substructures and wrong turns appear.
For example:
`c1ccccc1Oc1ccccc1F(C1C=CC=C2C=CC=CC=12)N(C1C=CC=C2C=CC=CC=12)Oc1ccccc1Br(C1C=CC=C2C=CC=CC=12)P[C-]BC1CCCC1Cl(C1C=CC=C2C=CC=CC=12)O`

`NC1CCCCC1[SiH2]C1CCCCC1PC1CCCC1CBrBrC1CCCCC1BNC1CCCCC1F[Br+]C1CCCC1`

For Indigo Service:
```bash
curl -X POST "http://localhost:8002/v2/indigo/render" -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"output_format\": \"image/png\", \"struct\": \"c1ccccc1Oc1ccccc1F(C1C=CC=C2C=CC=CC=12)N(C1C=CC=C2C=CC=CC=12)Oc1ccccc1Br(C1C=CC=C2C=CC=CC=12)P[C-]BC1CCCC1Cl(C1C=CC=C2C=CC=CC=12)O\"}"
```

```bash
curl -X POST "http://localhost:8002/v2/indigo/render" -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"output_format\": \"image/png\", \"struct\": \"NC1CCCCC1[SiH2]C1CCCCC1PC1CCCC1CBrBrC1CCCCC1BNC1CCCCC1F[Br+]C1CCCC1\"}"
```

**Expected behavior**
Rendered images without overlapping structures.

**Actual behavior**
