Using the Shared Edit tool turns true arcs into a series of straight lines

Description

If you use the Shared Edit tool on a feature that contains a true arc (parametric curve), the true arc becomes a series of straight lines and vertices.

Cause

The Shared Edit tool automatically integrates the selected features. Since the integrate process creates common vertices among features, the parametric curve is no longer a true arc because it now uses vertices connected by straight lines.
