Subject: [PATCH] Sketcher: transfer constraints on conic's mid point to the
 newly created conic arc (e.g. ellipse arc)" -m "Fixes #15860" -m "When
 spliting a sketch curve, constraints on the original curve are transferred to
 the newly created curve. The original code did not consider the constraints
 on the center point of an ellipse arc.
