Issue with Automatic Addition of Hydrogen Atoms

To Whomever it may Concern,

I noticed an issue with the, “add hydrogens,” feature in the build menu. For a structure with sp^2 carbons, i.e. coronene, if you start with just carbon atoms and try to add the hydrogens some of the edge carbons are treated as sp^3 hybridized. Not sure if this is an issue general to all sp^2 carbon structures, but I’ve included a relevant structure for testing.

Best,
Devin
