Bug: hydrogen count on pasting radicals as SMILES

I've reported this before for v.20, but just so it appears in one place. :) When pasting the radical SMILES strings "[CH3]" or "[CH2]" directly into ChemDraw, it incorrectly gives a CH4 molecule. However, when I draw a methyl CH3 radical myself and then copy it as SMILES, it does correctly give the string "[CH3]".

Strings that do work correctly include "[NH]", "[OH]", "[PH2]", "[SiH3]", so it seems this may mainly or only affect carbon. "[CH3CH2]" also works correctly.
