Mesylate Abbreviation Incorrect

[starmaid]

Expected Behavior: Mesylate group abbreviated with Ms

Observed Behavior: Mesylate is being abbreviated with an acetate Ac symbol. I've tried a few combinations with different atoms connecting the mesylate to the rest of the molecule, but it seems to always abbreviate with Ac.

Fix could be in here /src/DrawerBase.js : initPseudoElements(). Still not sure what the fix is.
