Describe the bug Unable to add hydrogens for aromatic bonds outside the ring - system throws exception

Steps to Reproduce

1. Load from file: Unable to add hydrogens for aromatic bonds outside the ring - system throws exception.zip (unzip first)
2. Press Add/Remove explicit hydrogens button

Actual behavior System throws exception: IndigoException: element: can not calculate implicit hydrogens on aromatic C, charge 0, degree 1, 0 radical electrons uat.test.lifescience.opensource.epam.com-1705525259112.log

Expected behavior

This is not query related issue. If you add 'aromatic' for any atom to use query molecule mode you can see that it will work

[AliaksandrDziarkach]

I have no idea why "aromatic" bond placed in query bonds in ketcher. This is just a normal bond like single/double/triple. For example: if you add cyclohexane and change all bonds to aromatic - after change last bond to aromatic it will be re-drawn as aromatic benzene.

Should not throw exceptopn

No exception now - good, but works wrong (Version 1.18.0-rc.5.0-gb21ab5ad5-wasm32-wasm-clang-12.0.0) Actual behavior:
