Describe the bug
I want to map the atoms between two molecules based on MCS. For this particular molecule, I get an error, that the substructure is not matched.

To Reproduce

foo = Chem.MolFromSmarts('[#7]1(-&!@[#6&!R](-,=;!@[#1,#8;!R])=,-;!@[#8,#1;!R])-&@[#6](-&@[#6]2(-&@[#6](-&@[#6]-&@1(-&!@[#1&!R])-&!@[#1&!R])(-&@[#6]-&@2(-&!@[#1&!R])-&!@[#1&!R])-&!@[#1&!R])-&!@[#1&!R])(-&!@[#1&!R])-&!@[#1&!R]')
Chem.SanitizeMol(foo)
foo.HasSubstructMatch(foo) # returns False

Expected behavior
I expect mol.HasSubstructMatch(mol) to return True.

Configuration (please complete the following information):

• RDKit version: 2024.03.3
• OS:
  NAME="Rocky Linux"
  VERSION="9.4 (Blue Onyx)"
• Python version (if relevant):
• Are you using conda? mamba
• If you are using conda, which channel did you install the rdkit from? conda-forge
