Summary	0028216: Intersection of a face and a solid is broken up leading to empty result of Boolean common operation
Description	In the appended case the intersection of a face and a solid leads to 3 not connected edges. It would be expected that they touch each other. When doing a boolean common operation the result is an empty compound. All checks say that the shapes are valid.
