Summary0003160: New octagon collapses
DescriptionInserting an octagon in sketcher behaves unexpectedly when the centre is on the origin and the radius is placed on the X axis; it is created with zero size. Subsequently trying to set the radius of the circumscribing circle is not allowed; conflicting constraints.

After some experimenting, it seems to only happen when the suggested constraints are point on object, and horizontal.
