Simplified editor: adding shared member special character & is failing

Summary:

Simplified editor: adding shared member special character & is failing. The error is 'base member specified for shared member could not be located'

You can add this on the classic editor or SmartView Add-ins. I have iterated in both SWP and EPBCS - they exhibit the same behavior with multiple iterations.
