Summary0029426: Extrema algorithm fails to find minimal distance between Circle and Sphere
DescriptionThe solution found by Extrema algorithm on the attached geometries is not minimal. Although, for the trimmed circle the found solution is more correct.

The problem has been detected in the test cases bugs modalg_7 bug26883_* while making patch for the issue 0028599.
